Gnus/5.130006 (Ma Gnus v0.6) Emacs/24.4 (gnu/linux) |
ps-print.el generates invalid PostScript when called from Gnus to print
an article (gnus-summary-print-article). Some glyphs are missing from
the BitmapDict as well as from Exxxx dictionaries.
To reproduce the bug let there be a buffer named "ZAŻÓŁĆ" containing the
following string:
Zażółć gęślą jaźń
In this buffer evaluate the following form:
(let ((ps-left-header (list "fubar")))
(ps-spool-buffer)
(ps-despool "/tmp/fubar.ps"))
When viewing the file under gv (gv 1:3.7.4-1, ghostscript
9.06~dfsg-2+deb8u1, on Debian jessie). There is an empty grey header
box, and the following error message is displayed on the page.

Please find the faulty fubar-bad.ps and fubar-good.ps attached. The
latter has been generated after applying the patch that will follow this
message. The patch has been created on the master branch.
I've tested it only on Debian 8 with bdf fonts, so please make sure the
patch won't introduce any regressions.
