Hi, evergyone I found a instruction in context wiki (http://wiki.contextgarden.net/Chinese) in this page , it says: If you have Context 2005.12.19, you only have to get the fonts. 1.You need some Chinese (TrueType) fonts; you may want to get FangSong, HeiTi, KaiTi and SongTi. Put those e.g. into $TEXMF/fonts/truetype/chinese/. -----------finished 2.Use Hans Hagen's experimental ttf2uni.rb script to create .map, .tfm and .enc files. You can then put the files e.g. to $TEXMF/fonts/tfm/chinese/ (*.tmf files), $TEXMF/fonts/enc/chinese/ (*.enc files, they are basically the same for all fonts) and to $TEXMF/fonts/map/chinese/. -----------wondering!!!! I have downloaded the file ttf2uni.rb to my local machine. But how can I creat such .map ,.tfm and .enc files via it? 3.You may now need to update the hash TeX uses to find the files; using teTeX this is done by running texhash. 4.How you can run your Hello World program: could anyone be kindly to offer me a list of detail instructions about how to do? thank you!
