Thai characters include vowels, which are written in various positions relative to consonants, and "tones" which indicate tonal vocalization used in the enunciation of characters, such "tones" also having certain selected positions relative to characters and associated vowels. Current data processing equipment for generating Thai supports fifty-three characters, five tones, two lower vowels and six upper vowels. Fig. 1 illustrates the various, possible positions of tones and vowels relative to each other and to an associated character. At present, each tone and each vowel is represented by one byte, with the result that each complete Thai character requires at least three bytes.
