The most important thing you need to remember is that UnionWay software is fully modularized. The basic kernel program (called Double-Byte Manager) already provides all features required to support multiple Asian languages, UnionWay TrueType fonts and different input methods. Each higher package simply contains additional modules that the lower package(s) do not. For Chinese input methods, it provides single word input methods for pinyin and zhuyin. For a Japanese input method, it provides the kana to kanji method. For a Korean input method, it provides the hangul method. ProPack adds UnionWay's TrueType fonts, more input methods, and the UWTTConvert and FontMaker utilities. For Chinese input methods, it provides single word and phrase input methods for pinyin and zhuyin as well as the English to Chinese method. For Japanese input methods, it provides the romaji to kanji input method in addition to the kana to kanji method. Finally, the Korean input methods hangul and hanja are both supplied with the Korean ProPack version.

The UWTTConvert utility allows you to generate single byte TrueType fonts from any double byte TrueType font. This function is very useful when you need to use CJK characters in a Windows application which is designed to only handle single byte TrueType fonts; for example, the text rotation feature of a graphics program. The FontMaker utility allows you to edit any UnionWay TrueType fonts.
