Hi Alex,
The chinese glyphs are present in the bookmarks because you are using my
branch. :-) They are missing in the text because you don't have a font
installed which contains those glyphs.
You can download a patch from here:-
http://chuzzlewit.co.uk/chinese.patch.gz
It is too large for email, it contains the UnifontMedium font which contains
the Chinese glyphs, typographically it is not the best font, a proper type 1
font which contains CJK glyphs would be better, also it does not do bold
glyphs.
Gunzip the file then use git apply. There will be two new files in the devpdf
directory which should be added to git.
Cheers
Deri
