From a lookup table, you can search for and select the Chinese characters you want to input. Three kinds of lookup tables are available:
Lookup table with native encoding, such as EUC_TW in the zh_TW/zh_TW.EUC locale, or BIG5 encoding in the zh_TW.BIG5 locale
Lookup table with UNICODE encoding
Lookup table for special characters, such as Greek letters or Mathematical symbols
