This surprises me, since I've mentioned it in the README file of the
CJK package, already in the second paragraph.

I think this is a bug in pdfeTeX. IIRC, this or a similar problem has
been mentioned on the pdftex mailing list.
Please check the pdftex mailing list archive and try to download the
latest version from Sarovar -- probably compiling with the `-g -O0'
compiler flags to activate debugging, and to disable optimization. In
case this doesn't fix the issue, submit a bug report to the pdftex
maintainers.

Looking into arialuni version 0.84 and cyberbit 1.1 (this is what I
have on my box) I can see that the latter has a real glyph for
uniFF0C, while the former uses the `comma' glyph as a subglyph. Maybe
this doesn't work properly with pdftex.

As a workaround I suggest that you use the subfonts.pe script from CJK
4.6.0 (or the latest snapshot) to split arialuni.ttf in a set of Type 1
subfonts. Be warned that it takes hours even on a fast computer until
the conversion has finished! The proper SFD file is Unicode.sfd; Some
time ago I've posted an updated version to this list; you might find
it also in the `freetype1-contrib' CVS repository (available from
savannah.gnu.org/projects/freetype).
