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. While T.61 continues to be supported in modern versions of X.500 and X.509, it has been deprecated in favor of Unicode. 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some standards using ASN.1 (for example in RSA Security's PKCS #9), the 1988-11 version of the T.61 standard itself was superseded by a never-published 1993-03 version; the 1993-03 version was withdrawn by the ITU-T.〔(【引用サイトリンク】title=Recommendation T.61 )〕 The 1988-11 version is still available.〔 == References == 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ITU T.61」の詳細全文を読む スポンサード リンク
