    Allow font caches to contain newer version numbers
    
    Use the version number inside the cache file to mark backward compatible
    changes while continuing to reserve the filename number for incompatible
    changes.

    Unify directory canonicalization into FcStrAddFilename.
    
    Instead of making filename canonicalization occur in multiple places, it
    occurs only in FcStrAddFilename now, as all filenames pass through that
    function at one point.

    Move Free family names to bottom of respective aliases. (bug 7429)
    
    The FreeSans, FreeSerif and FreeMono fonts cover a large number of
    languages, but are of generally poor quality. Moving these after fonts which
    cover specific languages but which have higher quality glyphs should improve
    font selection.

    Limited FC_DEBUG documentation (just shows values and vague idea of what
    they''re related to). Also document \ escape syntax for font names,
including
    how family name and values have different escape requirements.

    Guess that mac roman names with lots of high bits are actually SJIS.
    
    Many Japanese fonts incorrectly include names tagged as Roman encoding and
    English language which are actually Japanese names in the SJIS encoding.
    Guess that names with a large number of high bits set are SJIS encoded
    Japanese names rather than English names.

    Prefer Bitstream Vera to DejaVu families.
    
    DejaVu is a modified version of Bitstream Vera that covers significantly
    more languages, but does so with spotty quality, lacking hinting for many
    glyphs, especially for the synthesized serif oblique face. Use Bitstream
    Vera (where installed).

Given that the glyphs that exist in Vera all exist and are hinted in
Deja, isn''t this only going to result in opening both files if glyphs
not in Vera are required, instead of only opening Deja?

Ie, does it really change which glyphs get used?

(This isn''t a rhetorical question; I could be relying on a bad
assumption, such as how often fallbacks are used.  And I presume it
would make more difference if there were other familied between Vera
and Deja in the lists....)

The main effect is to select Vera for the serif oblique face. Doing the
obliquing in fontconfig preserves most of the value from the hints,
making this a better looking face.

Unfortunately, TrueType fonts are effectively required to provide Latin
glyphs, which leaves many of the non-Latin faces including truely
objectionable Latin glyphs. So, to allow DejaVu to be used for Latin
glyphs, it must be placed before all non-Latin faces.

With the ability to ban glyphs and edit language support, we can rethink
this whole issue.

Also, I would like to see the DejaVu developers split their font across
writing system boundaries so we can correctly arrange them with relation
to other fonts. Right now, when you select DejaVu for Latin, you''re
forced to live with DejaVu for everything else. Ick.

It''s almost as if people haven''t learned the lesson of
ArialUnicode yet.

This change is causing bad rendering (missing glyphs) for people using
KDE / QT with czech (as reported on
http://qa.mandriva.com/show_bug.cgi?id=25648 ).

Given :
1. that the DejaVu founder (?t?p?n Roh) *is* Czech
2. some major DejaVu contributors use KDE
3. none of the other distros which use DejaVu (in full of LGC form) report
this problem (and it is taking a beating in FC6 tests at least)

... I seriously doubt the bug is in DejaVu (but probably in mandriva''s
KDE/QT stack)

The lack of any thorough investigation in the mandriva bug is
disappointing to say the least. If you actually believe the problem is in
the font you could at least contact the dejaVu team (next release is in
two days)

Given the broken way Qt uses fontconfig, I''m not surprised.  A few
weeks
ago, my fontconfig config file to make DejaVu LGC override Bitstream
Vera caused s p a c e d   o u t monospace fonts in KDE.

And I never said it was.

I say the change to favorize Bitstream Vera instead of DejaVu caused the
bug for people using QT/KDE. And this change is only in fontconfig 2.4.0
which has been integrated in very few distributions at the moment.

And our final distribution release is now. Which is why I didn''t have
time to investigate further (moreover with so vague bug report as I got
and nobody able to give a testcase) and I switched back to DejaVu by
default. Moreover, KDE/QT has always been very "special" regarding
fontconfig font alias.

My mail is to inform Keith Packard and other fontconfig developers about
this issue, introduced by fontconfig 2.4.0, not to do any polemic about
fonts.
