Abstract: An encoding scheme of inputting Xiangxi square Hmong language characters is put forward after the structure features and the method of compounds splitting are analyzed.This scheme is based on inputting the whole letters of Chinese pinyin components.The code mapping table is designed.Taking Duoduo input soft generator as a tool,the input soft based on IMM-IME architecture and setup program are implemented.Test result shows that the input method based on the above scheme is easy to learn and use,and can effectively solve the problem of inputting Xiangxi square Hmong language characters into computer.

Key words: Xiangxi square Hmong language characters, input method, code mapping table, IMM-IME architecture
