{{Short description|Extended character encoding for Standard Cantonese}}

The '''Hong Kong Supplementary Character Set''' ({{lang|zh-Hant|香港增補字符集}}; commonly abbreviated to '''HKSCS''') is a set of [[Chinese character]]s – 4,702 in total in the initial release—used in [[Standard Cantonese|Cantonese]], as well as when writing the [[List of places in Hong Kong|names of some places in Hong Kong]] (whether in [[written Cantonese]] or [[Vernacular Chinese|standard written Chinese]] sentences).<ref>[http://www.gov.hk/en/about/helpdesk/faq/other/index.shtml FAQs about GovHK Online Services – Other Technical Questions and Trouble Shooting]</ref>

It evolved from the preceding '''Government Chinese Character Set''' ({{lang|zh-Hant|政府通用字庫}}) or '''GCCS'''. GCCS is a set of supplementary [[Chinese character]]s coded in the user-defined areas of the [[Big5]] character set.  It was originally used within the [[Government of Hong Kong|Hong Kong Government]] and later used by the public. It later evolved into Hong Kong Supplementary Character Set when the characters in the set were submitted to [[ISO-10646]] for coding.

== History and versions ==

The HKSCS has gone through a few iterations.<ref>{{Cite web |url=https://www.ogcio.gov.hk/en/business/tech_promotion/ccli/hkscs/development.htm |title=OGCIO - Development of HKSCS |access-date=21 August 2017 |archive-date=22 August 2017 |archive-url=https://web.archive.org/web/20170822054528/https://www.ogcio.gov.hk/en/business/tech_promotion/ccli/hkscs/development.htm |url-status=dead }}</ref>

HKSCS versions up to HKSCS-2008 are encoded in [[Big5]] (Big5-HKSCS,<ref name="iana">{{cite web | url=https://www.iana.org/assignments/character-sets/character-sets.xhtml | publisher=IANA | title=Character Sets}}</ref> big5hk)<ref>{{Cite web|url=http://infocenter.sybase.com/help/topic/com.sybase.infocenter.dc34789.1550/html/ocsinunx/CIHEBHFB.htm|title = SDK components}}</ref> and [[ISO 10646]] ([[Unicode]]).

==== GCCS ====

Due to the inherent differences between [[standard written Chinese]] and [[written Cantonese]], the Government of Hong Kong recognised the need for a standardised set of ''proprietary'' characters that would allow for the streamlining of electronic communication; at the time, the [[Big5]] Chinese encoding scheme did not contain a vast majority of these characters (some were erroneously cross-listed with similar characters).

The Government Chinese Character Set ({{lang|zh-Hant|政府通用字庫}}) or GCCS  was thus developed by the government.  The character set consists of Chinese characters commonly used in Hong Kong.  Some characters are [[Cantonese language|Cantonese]]-specific, while some are alternative forms of characters.  The set is not well-organised and the characters are not closely examined.

==== HKSCS-1999 ====

Subsequently, the HKSCS-1999 (HKSCS 1999 specification) was developed. 106 GCCS characters were removed in HKSCS-1999 as a result of unification, and their Big5 code points are reserved for compatibility.<ref name="big5cmp">{{cite web|title=Big5CMP.txt |url=http://www.ogcio.gov.hk/en/business/tech_promotion/ccli/terms/doc/big5cmp.txt |archive-url=https://archive.today/20160913171131/http://www.ogcio.gov.hk/en/business/tech_promotion/ccli/terms/doc/big5cmp.txt |archive-date=13 September 2016 |url-status=dead |df=dmy-all }} Found at [http://www.ogcio.gov.hk/en/business/tech_promotion/ccli/archive/archive_mapping_table_2008.htm Mapping table - HKSCS-2008]</ref><ref name="HKSCS-2004-Annex4">{{cite web|url=http://www.ogcio.gov.hk/en/business/tech_promotion/ccli/terms/doc/e_annex4_2004.pdf|title=HKSCS-2004 Annex IV.

==== HKSCS-2001 and HKSCS-2004 ====

Following the acceptance of HKSCS-1999, newer revisions were released in 2001 (adding 116 new characters) and in 2004 (adding 123 new characters), totalling 4,941 characters.<ref name="big5cmp"/>

Starting from HKSCS-2004, all characters previously using the [[Private Use Area]] (PUA) section of Unicode (via [[Code page 950#Private Use Area usage|Microsoft's mapping of the Unicode PUA over the private-use ranges of Big5]]) are remapped, with many of them reassigned to characters in the [[Supplementary Ideographic Plane]], such as in the [[CJK Unified Ideographs Extension B]] or [[CJK Compatibility Ideographs Supplement]] Unicode [[Unicode block|blocks]].<ref>{{cite web|title=Big5-HKSCS:2004|url=http://moztw.org/docs/big5/table/hkscs2004.txt}}</ref>  However, to preserve compatibility with programs that generated PUA code points, the already-allocated code points are reserved, and no new characters will be mapped to the private use area.

==== HKSCS-2008 ====

Since around 2005, many Hong Kong and [[Macau]] websites have switched encoding from Big5-HKSCS to Unicode, including [[HKGolden]].

The last edition of HKSCS to encode all of its characters in Big5 was HKSCS-2008.<ref name="irgn2430"/>

=== Unicode subsets (2015 onwards) ===

==== HKSCS-2016 ====

By 2015, efforts were underway in Hong Kong to migrate away from Big5-HKSCS and towards a defined subset of Unicode, at the time tentatively termed the ''Hong Kong Character Set (HKCS)''. This was planned to be published by the end of 2015 as "HKCS-2015", and to have four parts differentiated by different [[Unihan]] source prefixes:<ref name="irgn2074">{{cite web |url=https://www.unicode.org/irg/docs/n2074-HKCS.pdf |id=[[ISO/IEC JTC 1|ISO/IEC JTC1]]/[[ISO/IEC JTC 1/SC 2|SC2]]/WG2/[[Ideographic Research Group|IRG]] N2074 |last=Lu |first=Qin |title=The Proposed Hong Kong Character Set |date=2015-06-08}}</ref>

* Source prefix {{code|H}} followed by Big5 [[hexadecimal]]: [[character repertoire]] of HKSCS-2008 in the narrow sense
* Source prefix {{code|HB}} followed by Big5 hexadecimal: character repertoire of Big5-ETEN
* Source prefix {{code|HC}} followed by a four-digit decimal incremental [[accession number (cultural property)|accession number]]: post-2008 vertical extensions (i.e. newly submitted [[CJK Unified Ideographs]])
* Source prefix {{code|HD}} followed by hexadecimal Unicode code point: post-2008 horizontal extensions (i.e. the addition of a Hong Kong reference glyph and source reference to an existing CJK Unified Ideograph)

In particular, 22 horizontal extensions were already planned for inclusion as of June 2015. These were all minor [[itaiji|variants]] of existing Big5 characters containing the 昷/𥁕, 兑/兌 and 吿/告 components, for which Hong Kong font conventions were closer to those of [[mainland China]] than to those of [[Taiwan]], but for which the preferred versions had been encoded separately from the Big5 versions in the [[Unified Repertoire and Ordering]] due to the source separation rule.<ref name="irgn2074"/><ref name="lunde-iicore">{{cite web |url=https://ccjktype.fonts.adobe.com/2018/02/exploring-iicore-part-4.html |title=Exploring IICore—Part 4 |work=CJK Type Blog |last=Lunde |first=Ken |author-link=Ken Lunde |publisher=[[Adobe Inc]]}}</ref> Of these 22 characters, 14 were considered "core" characters for Hong Kong use.<ref name="lunde-iicore"/>

By November, a total of 78 requested additions to HKSCS had been received by the Hong Kong government, all of which already existed in Unicode. By this point, the planned horizontal extension was being referred to as an "HKSCS" version, rather than as "HKCS".<ref name="irgn2098">{{cite web |url=https://www.unicode.org/irg/docs/n2098-HKSARActivityReport.pdf |id=[[ISO/IEC JTC 1|ISO/IEC JTC1]]/[[ISO/IEC JTC 1/SC 2|SC2]]/WG2/[[Ideographic Research Group|IRG]] N2098 |date=2015-11-16 |title=Activity Report of the Hong Kong Special Administrative Region (HKSAR)}}</ref> Ultimately, HKSCS-2016 added a total of 24 characters relative to HKSCS-2008, 22 of which were the source-separated variants of existing Big5 characters.<ref name="lunde-iicore"/> Since all 24 characters already existed in Unicode, all received a source reference prefixed with {{code|HD}}; the {{code|HC}} source prefix was not used.<ref>{{cite web |url=https://www.unicode.org/reports/tr38/#kIRG_HSource |title=kIRG_HSource |work=Unicode Han Database (Unihan) |institution=[[Unicode Consortium]] |last1=Lunde |first1=Ken |author-link1=Ken Lunde |last2=Cook |first2=Richard |date=2024-07-31 |version=Revision 37}}</ref>

As such, the characters added in HKSCS-2016 are referenced to Unicode only, and were not added to the Big5 extension.<ref name="irgn2430">{{cite web |url=https://www.unicode.org/irg/docs/n2430r-MSCS.pdf |title=Submission of Macao's Vertical Extension (UNC Characters), Horizontal Extension, and IVSes Registration for MSCS |author=Macao Special Administrative Region Government |date=2020-07-02 |orig-date=2020-06-11 |id=[[ISO/IEC JTC 1/SC 2]]/WG 2 [[Ideographic Research Group|IRGN]] 2430}}</ref>

==== Amendments to HKSCS-2016 ====

{{as of|September 2025}}, four additional characters have been approved by the Chinese Language Interface Advisory Committee (CLIAC) for inclusion in HKSCS as amendments following the publication of HKSCS-2016: {{unichar|5C83|name=none}} in January 2019, {{unichar|2D25D|name=none}} and {{unichar|2BB37|name=none}} in February 2021, and {{unichar|35E9|name=none}} in February 2025.<ref>{{cite web |url=https://www.ccli.gov.hk/en/hkscs/what_is_hkscs.html |title=What is HKSCS? |work=Common Chinese Language Interface |access-date=2025-09-23}}</ref>

==== Macao Supplementary Character Set ====

Similarly to Hong Kong's situation, there are also characters that are needed by [[Macau]] but included in neither Big5 nor HKSCS, hence, the ''Macao Supplementary Character Set'' was developed, building on HKSCS with additional Unicode-mapped characters. The first batch of 121 MSCS characters were submitted for addition to or horizontal extension in Unicode (as appropriate) in 2009.<ref name="irgn1580">{{cite web |url=https://www.unicode.org/irg/docs/n1580r-MISCS.pdf |title=Submission of Characters from Macao Information Systems Character Set |author=Computer Chinese Characters Encoding Workgroup |date=2009-06-12 |id=[[ISO/IEC JTC 1/SC 2]]/WG 2 [[Ideographic Research Group|IRGN]] 1580}}</ref> At the time, the term ''Macao Information Systems Character Set'' (''MISCS'') was in use for the entire character set, while "MSCS" referred more narrowly to the additional characters only.<ref name="irgn1580"/>

The first final version of MSCS, MSCS-2020, was established in 2021, and uses the following [[Unihan]] source prefixes.<ref name="irgn2430"/><ref name="irgn2456"/> Although the potential scope of these source prefixes collectively comprises a superset of HKSCS-2016, "MSCS" in a strict sense does not cover the Big5 or HKSCS characters (since it is intended to be combined with HKSCS) except those which are used as base characters for [[Variation Selectors Supplement|ideographic variation sequences]].<ref name="irgn2430"/><ref name="irgn2456">{{cite web |url=https://www.unicode.org/irg/docs/n2456-MacaoSARActivityReport.pdf |id=[[ISO/IEC JTC 1|ISO/IEC JTC1]]/[[ISO/IEC JTC 1/SC 2|SC2]]/WG2/[[Ideographic Research Group|IRG]] N2456 |date=2021-03-14 |title=Macao SAR Activity Report (IRG Meeting #56)}}</ref>

* Source prefix {{code|MA}} followed by Big5 hexadecimal: character repertoire of HKSCS-2008 in the narrow sense (same as {{code|H}})
* Source prefix {{code|MB}} followed by level number and Big5 hexadecimal: character repertoire of Big5-ETEN (same as {{code|HB}})
* Source prefix {{code|MC}} followed by a five-digit decimal incremental accession number: Macau-specific vertical extensions. This prefix had initially been {{code|MAC}} in 2009,<ref name="irgn1580"/> but was shortened to {{code|MC}} for vertical extensions in 2020, while horizontal extensions had their source references replaced with {{code|MD}} references.<ref name="irgn2430"/>
* Source prefix {{code|MD}} followed by hexadecimal Unicode code point: Macau-specific horizontal extensions
* Source prefix {{code|MDH}} followed by hexadecimal Unicode code point: horizontal extensions from HKSCS-2016 (same as {{code|HD}})
* Source prefix {{code|ME}} followed by hexadecimal Unicode code point and a three-digit decimal number: used for variation sequences registered in the [[Variation Selectors Supplement|Ideographic Variation Database]] (IVD)

== Compatibility ==

=== Operating systems ===

In [[Microsoft Windows]] 98, NT 4.0, 2000, XP, HKSCS support can be enabled using Microsoft's patch. In Microsoft's implementation, application using [[code page 950]] automatically uses a hidden [[code page 951]] table for the [[Big5]] encoding of the HKSCS extensions. The table supports all code points in HKSCS-2001, except for the compatibility code points specified by the standard.<ref name="cp951-msblog">{{cite web|last1=Steele|first1=Shawn|title=CP 951 & HKSCS|url=https://blogs.msdn.microsoft.com/shawnste/2007/03/12/cp-951-hkscs/|website=I'm not a Klingon|publisher=MS Dev Blog|access-date=13 September 2016}}</ref> In addition, the MingLiU font is altered using Microsoft's patch. This patch is known to create conflicts in applications such as [[Microsoft Office]], or any application using fonts supporting [[simplified Chinese characters]] (e.g.: [[SimSun]]).  If the target environment contains custom font mapped to the code points affected by Microsoft's patch, the custom fonts can undo Microsoft's patch. Furthermore, the patch breaks EUDC Editor supplied with the affected versions of Windows.<ref>[http://www.cccl.com.hk/ccclnew/cccllee/cccllee18.html 華通資訊網: 小心！有人悄悄換掉了你的Windows系統字型]</ref> Starting with [[Windows Vista]], HKSCS-2004 characters are only supported as Unicode 4.1 or later; however, HKSCS-2001 and HKSCS-1999 characters are supported as Big5-HKSCS and Unicode, but Big5-HKSCS is available only if set "Language for non-Unicode programs" to "Hong Kong" or "Macau".<ref>[http://www.microsoft.com/hk/hkscs/ Microsoft: Hong Kong Supplementary Character Set – Support for Windows Platform]</ref><ref> {{Cite web |date=2014-02-27 |title=Big5-HKSCS編碼初探(上)-黑暗執行緒 |url=https://blog.darkthread.net/blog/about-hkscs-1/ |access-date=2024-09-03 |website=blog.darkthread.net |language=en}}</ref> All characters are assigned standard, non-[[Private Use Area#Private use characters|PUA]] codepoints. The characters are displayed with the [[MingLiU]] font, and these characters can be entered via the keyboard. The patch that provides [[Big5]] encoding of HKSCS is unsupported in Windows Vista and later. A utility provided by Microsoft is available to convert HKSCS and Unicode PUA-encoded characters to Unicode 4.1 version.<ref>[http://www.microsoft.com/downloads/details.aspx?FamilyID=0e6f5ac8-7baa-4571-b8e8-78b3b776afd7&DisplayLang=en Microsoft Character Code Conversion Routines For HKSCS-2004]</ref> In 2010, Microsoft published a HKSCS-2004 patch for Windows XP and Windows Server 2003.<ref>[http://www.microsoft.com/download/en/details.aspx?id=10109 Windows XP Font Pack for ISO 10646:2003 + Amendment 1 Traditional Chinese Support]</ref> It replaces Windows XP version of MingLiU, PMingLiU, and MingLiU_HKSCS (if HKSCS-2001 patch was applied) with Windows 7 version of MingLiU, PMingLiU and MingLiU_HKSCS. In addition, MingLiU-ExtB, MingLiU_HKSCS-ExtB and PMingLiU-ExtB fonts will be added onto target system. However, IME is not updated as it was in the case of HKSCS-2001 patch, and the fonts are from pre-release of Windows 7. For earlier versions of the OS, HKSCS support requires the use of Microsoft's patch, or the Hong Kong government's Digital 21's utilities.

HKSCS support was added to [[glibc]] in 2000, but it has not been updated since then. HKSCS-2004 support is handled as Unicode 4.1 and later. For [[freedesktop.org]] setup, ''AR PL ShanHeiSun Uni'' font fully supports HKSCS-2004 since 0.1-0.dot.1, with latest revision of HKSCS-2004 supported in version 0.1.20060903-1. Modern desktop distributions (e.g. Ubuntu) include [[Arphic Technology]]'s HKSCS-compliant UKai and UMing fonts out of the box when Traditional Chinese Language support is selected during installation. They can also be installed manually at a later time.

[[Mac OS X]] 10.0–10.2 supports HKSCS-1999. 10.3–10.4 supports HKSCS-2001. Some of the letters added to HKSCS-2004 is supported via Unicode PUA in OS X 10.4. Starting with OS X 10.5, all the HKSCS-2004 characters are supported via standard Unicode 4.1 code points.

=== Applications and the Web ===

[[Mozilla]] 1.5 and above supports HKSCS, with HKSCS-2004 support added into Gecko 1.8.1 code base.<ref>[https://bugzilla.mozilla.org/show_bug.cgi?id=343129 Mozilla.org: Bug 343129  – Big5-HKSCS 2004 <==> Unicode Table Update]</ref> Unlike the above-mentioned patch, Mozilla uses its own code page table. However, the fix for bug 343129 does not support characters mapped to code points above Basic Multilingual Plane.<ref>[https://bugzilla.mozilla.org/show_bug.cgi?id=162431 Bug 162431 – add non-BMP Unicode (plane 1 and above. surrogate) support to charset encoder/decoder]</ref>

[[Qt (toolkit)|QT]] 3.x-based applications (e.g.: [[KDE]]) only support characters mapped to code points FFFF or lower. In QT4, characters outside BMP are supported via surrogates. Big5-HKSCS Text Codec supports HKSCS-1999 back in Qt-2.3.x, but it was too late in Qt development schedule to be officially included in the Qt-2.3.x series, so it was officially supported in Qt-3.0.1. HKSCS-2001 support was added in Qt-3.0.5.<ref>{{Cite web |url=http://doc.qt.nokia.com/latest/codec-big5hkscs.html |title=Qt 4.7: Big5-HKSCS Text Codec |access-date=10 November 2011 |archive-url=https://web.archive.org/web/20160304185145/http://doc.qt.nokia.com/latest/codec-big5hkscs.html |archive-date=4 March 2016 |url-status=dead }}</ref>

[[GNOME]] supports HKSCS characters in Unicode ranges, except those mapped to the Basic Multilingual Plane compatibility block. Patches to support characters mapped to above Basic Multilingual Plane was introduced during Pango 1.1.<ref>[https://bugzilla.gnome.org/show_bug.cgi?id=101081 Bug 101081 – Non-BMP (plane 1 thru plane 16) characters are not supported]</ref>

The [[WHATWG]] Encoding Standard (used by [[HTML5]]) includes HKSCS in its definition of Big5 (used even with the plain Big5 label). However, only its decoder uses all HKSCS extensions, while its encoder explicitly excludes those with lead bytes below 0xA1 (thus excluding most of the HKSCS extensions but including, for example, those inherited from [[Big5#ETEN extensions|Big5 ETEN]]).<ref>{{cite web |url=https://encoding.spec.whatwg.org/ |title=Encoding Standard |publisher=[[WHATWG]] |last=van Kesteren |first=Anne |author-link=Anne van Kesteren}}</ref> Newer browsers follow this standard, including [[Firefox]].
