Template:Short description Template:Infobox technology standard

T.61 is an ITU-T Recommendation for a Teletex character set. T.61 predated Unicode, and was the primary character set in ASN.1 used in early versions of X.500 and X.509 for encoding strings containing characters used in Western European languages.<ref>Template:Cite web</ref> It is also used by older versions of LDAP.<ref>Template:Cite web</ref> While T.61 continues to be supported in modern versions of X.500 and X.509, it has been deprecated in favor of Unicode. It is also called Code page 1036, CP1036, or IBM 01036.

While ASN.1 does see wide use and the T.61 character set is used on some standards using ASN.1 (for example in RSA Security's PKCS #9), the 1988-11 version of the T.61 standard itself was superseded by a never-published 1993-03 version; the 1993-03 version was withdrawn by the ITU-T.<ref name="t.61-itu-t">Template:Cite web</ref> The 1988-11 version is still available.<ref name="t.61-itu-t"/>

T.61 was one of the encodings supported by Mozilla software in email and HTML until 2014, when the supported encodings were limited to those in the WHATWG Encoding Standard (although T.61 remained supported for LDAP).<ref>Template:Cite web</ref>

See ITU T.51 for a description of how the accents at 0xC0..CF worked. They prefix the letters, as opposed to postfix used by Unicode.
