character set mappings: tcs embodies what we know about the mapping of character sets into 10646/unicode and vice versa. there are three main parts: latin? alphabets described in desc.latin (from volume 1 of unicode) and encoded in tables in tcs.c, cyrillic described in the subdirectory cyr and encoded as tables in tcs.c, and han (chinese-japanese-korean ideographs) described in the subdirectory han and encoded in kuten*.c, big5.c, gb.c. other mappings are user-contributed. examples (and implied regression tests) are export/ex*.ok if you want to tweak the han mappings, han/README tells how. to make the han bitmap fonts, go to the subdirectory font and say mk fonts
