[pdftex] (fwd) tetex-bin: pdftex/pdflatex fails to subset embedded CJK TrueType font

[Hilmar Preusse]

Hi all,

here down in the Debian bug tracking system about two years ago we've
got the following bug report[1].
The example file and a log file is attached (log.txt is the screen
output). I've tried with pdfTeX from teTeX beta-2.99.4
(1.20b-rc3-2.2) and got the same results as in the report. The
mentioned arphic.map of cource was copied to the right place in the
tetex-beta tree. I've read pdftex-a.pdf and I couldn't found a
statement, that subsetting is not possible in some cases.
As mentioned in the report for compiling that file you need cjk-latex
installed and the Arphic "AR PL Mingti2L Big5" fonts installed (ttf
and tfm files). In Debian these fonst can be found in the packages
ttf-arphic-bsmi00lp and tfm-arphic-bsmi00lp.
Yes, there are encoding files as you can read in the log and the map
file looks correctly too (not subsetting).
Please keep the bug in Cc: (178717 at bugs.debian.org).

Thanks and Kind Regards,
  Hilmar Preuße

Hello,

At http://www.eecs.harvard.edu/~ccshan/debbugs/pdflatex/ is a document
containing some CJK characters.  The output of pdflatex when run on
"bug.tex" is the PDF file "bug.pdf".  This PDF file contains the
following fonts, as listed by the "pdffonts" command:

name                                 type         emb sub uni object ID
------------------------------------ ------------ --- --- --- ---------
UBZQKZ+URWPalladioL-Roma             Type 1       yes yes no       6  0
bsmi05                               TrueType     yes no  no       9  0
bsmi01                               TrueType     yes no  no      12  0
bsmi03                               TrueType     yes no  no      15  0

As this table shows, the CJK fonts bsmi* are embedded (as desired) but
not subsetted (undesired).  This seems to contradict the documentation;
for instance, page 15 of pdftexman.pdf.gz states that "in general
this [encoding] option is highly preferred and is required when
subsetting a TrueType font", and the encoding is indeed specified in
/etc/texmf/dvips/arphic.map (cjk-latex package).
