ISO/IEC 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 nearly identical to the national Thai standard TIS-620 (1990), the sole difference being that ISO 8859-11 defines hex A0 as a non-breaking space, while TIS-620 leaves it undefined. (In practice, this small distinction is usually ignored.)

ISO-8859-11 is not a registered IANA charset name despite following the normal pattern for IANA charsets based on the ISO 8859 series. However, the close equivalent TIS-620 (which lacks the non-breaking space) is registered with IANA.

The Microsoft Windows code page 874 as well as the code page used in the Thai version of the Apple Macintosh are extensions of TIS-620 — incompatible with each other, however.

As with all varieties of ISO 8859, the lower 128 codes are equivalent to ASCII. The additional characters are found in Unicode in the same order, only shifted from A1 to U+0E01 and so forth.
