ASMO 449
ASMO 449 is a, now technologically obsolete, 7-bit coded character set to encode the Arabic language. History This character set was devised by the now extinct Arab Standardization and Metrology Organization in 1982 to be the 7-bit standard to be used in Arabic-speaking countries. The design of this character set is derived from the 7-bit ISO 646 (version of 1973) but with modifications suited for the Arabic language. In code points ranging from 0x41 to 0x72 (hexadecimal), Latin letters were replaced with Arabic letters. Punctuation marks which were identical in the Latin and Arabic scripts remained the same, but where they differed (comma, semicolon, question mark), the Latin ones were replaced by Arabic ones. Only nominal letters are encoded, no preshaped forms of the letters, so shaping processing is required for display. This character set is not bidirectional and was intended to be used in right to left writing. Therefore, symmetrical punctuation marks ("(", ")", "", " , ", "" ...

ASMO 708
ISO/IEC 8859-6:1999, ''Information technology — 8-bit single-byte coded graphic character sets — Part 6: Latin/Arabic alphabet'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. It is informally referred to as Latin/Arabic. It was designed to cover Arabic. Only nominal letters are encoded, no preshaped forms of the letters, so shaping processing is required for display. It does not include the extra letters needed to write most Arabic-script languages other than Arabic itself (such as Persian, Urdu, etc.). ISO-8859-6 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429. The text is in logical order, so BiDi processing is required for display. Nominally ISO-8859-6 (code page 28596) is for "visual order", and ISO-8859-6-I (code page 38596) is for logical order. But in practice, and required for HTML and XML documents, ISO-8859-6 also stands for log ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
