I tested your program with another two Chinese ttf from win9x - MINGLIU.TTC and KAIU.TTF, here is the result:
MINGLIU.TTC -dynalab-MingLiU-medium-r-normal--0-0-0-0-m-0-iso8859-1 MINGLIU.TTC -dynalab-MingLiU-medium-r-normal--0-0-0-0-m-0-iso10646-1 KAIU.TTF -dynalab-DFKai-SB-medium-r-normal--0-0-0-0-m-0-iso8859-1 KAIU.TTF -dynalab-DFKai-SB-medium-r-normal--0-0-0-0-m-0-iso10646-1
It looks better then I added this line by hand:
MINGLIU.TTC -dynalab-MingLiU-medium-r-normal--0-0-0-0-m-0-big5-0
The spacing value 'm' still will cause delay with rxvt. Don't know why. :) The CJK ttf seem must use the 'c' value to avoid this problem. ps. how to fix the font's bugs if I want?
maybe fixing this program will be much easy. :)

How about using os2->ulCodePageRange1 to lookup the font encoding for supporting modren Unicode encoded CJK fonts? This idea is from another program. Then set their spacing value to 'c'. Here is a patch to do it:

After adopting this patch, I test it with arphic ttf again, the result is what I need:

then test it with baekmuk ttf:

and check ARIAL.TTF again:

Well, looks fine. :) This patch is ugly but maybe it is a start point.
Sorry for such long descriptions!

> does anyone know of a good TTF font editor on Linux?
The only outline font editor for Linux I know about is PfaEdit (http://pfaedit.sourceforge.net). It handles TrueType, PostScript Type 1, and various other formats. I'm not a font designer, and so I can't say whether or not PfaEdit really qualifies as "good" or not. It's been more than adequate for my own limited needs, though (mostly converting between formats and fixing font name problems).

pfaedit.
Supports both TTF and Type1 — even Chinese and Unicode ones.
