BTW, here's a screenshot of what I see on my ubuntu8.04 system
with fltk-2.x svn r6829 using Kochi Gothic:

I think you said you ran fltk's fonts app and it showed the
chars correctly with iLiHei.
1) Does the 'fonts' fltk test program show the new Kochi Gothic
font you installed? If not, maybe the font is not fully installed,
or the window/font manager needs a restart.
2) Did you try changing the example I posted to refer to "iLiHei"
instead of "Kochi Gothic"? (I think you know iLiHei works on
your system due to the successful run of the fltk2 'fonts'
test program)
3) If you still don't have luck, I'd suggest adding code that
checks for errors on all the font operations, eg. see if
the return value of fltk::font() is NULL.
FWIW, I ran strace(1) on the app to see what it was doing,
and on my system it looks like it's loading the truetype
version of the kochi font:
# strace ./foo
