Hi,

I'm a member of OpenPrinting, the standardize organization of *nix printing.
Printing-Japan ML is our discussion ML in Japanese.
I'll roughly translate the e-mail henrich_d attached.


This e-mail is written by Koji Otani, implementer of the PDF workflow.

----------------------------------------------------------------
OOo make wrong PS data with embedded font, but this problem caused only in
PDF workflow.

(Translator Remark: PDF workflow is OpenPrinting's new printer workflow.
Final goal is all of applications creates PDF instead of PS, and CUPS
filters handles PDF, because PDF is light, Page-oriented, any other good
feature from printing point of view.
Currently, some distribution, especially Debian Lenny (or later) and
Ubuntu 8.10 (or later) have supported this workflow)

Problem 1.
==========
OpenOffice.org has wrong login when it creates PS with embedded fonts.
In this case, OOo embed Type 42 (Truetype) fonts, however, some glyphs
of unprinterble characters (e.g. 「ご」 of IPA P Gothic) put with GID == 0
(for .notdef glyph only). This output is wrong.
And also Encoding is wrong. For example, when 「ご」is assigned in code == 1,
Encoding[1] should be related glyph name (glyph1), but OOo put the name to
Encoding[0]. Encoding[1] leave as .notdef.


Problem 2.
==========
Ghostscript can proceed that kind wrong PS (maybe it's a kind of bug).
  ( code --> .notdef --> GID==0)
So we have no problem without PDF workflow.
In the PDF workflow, PS data with problem 1 translated to PDF by Ghostscript
without any changes about font feature, then the PDF translated to PS.
In this process, this issue caused.

PDF workflow is need newer CUPS, so this issue depends on the CUPS version.
And we only have the problem in Debian Lenny (or later) / Ubuntu 8.10 (or
later), that's why only the two distros supports PDF workflow now.
