Typesetting Khmer

International audience Because of the complexity of Khmer script, up to now there has been neither typesetting system nor standard encoding for the Khmer language. In this paper are presented: (a) a complete type-setting system for Khmer based on TeX, METAFONT and an ANSI C preprocessor, as well as (b) a proposal of 8-bit encoding table for Khmer information interchange. Problems of phonic input, subscript and superscript positioning, collating order, spelling reforms and hyphenation are solved, and their solutions described. Finally an alternative solution using 16-bit output font tables is briefly sketched.
