Specifies a set of 183 coded graphic characters identified as Latin/Thai alphabet. Intended for use in data and text processing applications and also for information interchange. Contains graphic characters used for general purpose applications in typical office environments in at least the following languages: Thai, English and Latin. Some of the characters in this set are combining characters (see clause 6). This set of coded graphic characters may be regarded as a version of an 8-bit code according to ISO/IEC 2022 or ISO/IEC 4873 at level 1. May not be used in conjunction with any other parts of ISO/IEC 8859. If coded characters from more than one part are to be used together, by means of code extension techniques, the equivalent coded character sets from ISO/IEC 10367 or their corresponding G1 sets from 'ISO International Register of Coded Character Sets to be used with escape sequences', should be used instead within a version of ISO/IEC 4873 at level 2 or level 3. The coded characters in this set may be used in conjunction with coded control functions selected from ISO/IEC 6429. However, control functions are not used to create composite graphic symbols from two or more graphic characters (see clause 6).
