fontconfig priorities for non-LGC fonts

[Jens-Ulrik Petersen]

Hi,

We seem to be lacking space in the priority prefixes for fontconfig .conf files
for non-LGC fonts (aka nonlatin); maybe others too?

http://fedoraproject.org/wiki/Fontconfig_packaging_tips#Choosing_a_ruleset_n...

/usr/share/fontconfig/templates/fontconfig-priorities.txt

in that upstream's 65-nonlatin.conf is at the front of the 65-69 block.

This seems to largely make it impossible to override "nonlatin" fonts sometimes in fedora.

While we would like to address this upstream with restructuring the space
is there something we can do now in fedora for this for f13?

We need a fix before beta if we want to stop wqy-zenhei from overriding vlgothic for Japanese.

Thoughts, comments?

Jens

ps Overall 50-69 seems quite a narrow space for the range of fonts we have on hand now.

OTOH, this also make it very hard for a CJK font to mess with latin
font. I'm pretty sure this is the main reason latin and non-latin were
separated in upstream fontconfig. So, while I agree the current
situation is a dead-end, lifting constrains and hoping for people to
deal with it is likely to result in more problems. Someone needs to
write new sanity rules that can replace the current ones (hopefully, for
more than a few years)

From the few experiments I made, fontconfig does not actually sort on
the two first digits. It sorts on the full filename. So 65-0-foo will
probably sort before 65-nonlatin.conf
