ISO 8859-11
ISO 8859-11 is an 8-bit character encoding, part of the ISO 8859 standard. It covers the characters used for the Thai language. It was added in 1999 to the ISO 8859 standard, and is identical to the national Thai standard TIS-620, which dates back to 1990.The Microsoft Windows codepage 874 as well as the codepage used in the Thai version of the Apple Macintosh are an extension of TIS-620, however incompatible with each other.
As with all varieties of ISO 8859, the lower 7 bits are equivalent to ASCII. The additional characters are found in Unicode with the same outline, only shifted from A1 to 0E01 and so forth.
