23.0.60; Corrupted display. |

Date: |
Wed, 23 Jul 2008 01:34:36 +0200 |
After some use, Emacs display shows garbage characters instead of
normal text. Only those characters that are shown with the normal face
are replaced by garbage. Text shown as italics, bold, etc, remains
correct. I have no recipe to reproduce this. It usually happens while
reading news with Gnus, but I was unable to reproduce the problem by
duplicating the Gnus session (in particular, displaying again the
article that I was reading when the display got corrupted).

Here is some more info about this.
The display shows problems with font families Times and Helvetica. I use the
standard Times and Helvetica Type1 fonts on Windows XP. E.g., the Times Roman
font file is named TIR_____.PFM; the Helvetica file is HV_____.PFM.
Thanks for your extra information. I think this is related to the fact
that the Uniscribe font backend can only use opentype and truetype
fonts, but Windows by default defines font substitutions for Helvetica
and Times to map to the Truetype fonts "Arial" and "Times New Roman". So
the uniscribe backend picks these substitutes up, but somehow things get
confused so the Type-1 fonts end up being loaded. I've added some code
to specifically reject these substitutes, which are detected by
comparing the font's "full name" with the name used to load it.
Unfortunately this also catches many legitimate fonts, so I've had to
pick out these two specific problematic substitutions. If there are any
other specific fonts that cause this problem, then we will need to add
rules for them too.
