Hmm, weird. so the suggestion from nim-nim on the package review was wrong and the priority on our fontconfig l10n template won't effects reversely?

Unless fontconfig changed its behaviour my advice was correct. *However* it is only correct if the other packages you interact with limit themselves to the few audited fontconfig patterns. If they start being creative (and fontconfig gives people a *lot* of room to be creative) all bets are of.

I've almost given up on CJK font packages. At this stage if CJK packagers do not get together to agree on a common way to use fontconfig (and have Behdad proof it) there is no way to progress. Right now it's a "you have packaged a CJK font; go directly to bugzilla"

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Sorry for taking a long time to work on this.

I finally had a time to confirm the fontconfig behaviour and now see how it behaves on building fontsets in fontconfig. the example should be sufficient to explain how it works but not relevant to this font at all, sorry.

just having the rules in one file like:
<match>
  <test name="lang">
    <string>zh-cn</string>
  </test>
  <test name="family">
    <string>sans-serif</string>
  </test>
  <edit name="family" mode="prepend" binding="same">
    <string>AR PL UKai CN</string>
  </edit>
</match>

and

<match>
  <test name="lang">
    <string>zh-cn</string>
  </test>
  <test name="family">
    <string>sans-serif</string>
  </test>
  <edit name="family" mode="prepend" binding="same">
    <string>AR PL UKai HK</string>
  </edit>
</match>

the first one would behaves similarly to the rules named with the small number. the later one would be one named with the large number. here is the result how fontconfig modifies the pattern:

$ FC_DEBUG=4 fc-match "sans-serif:lang=zh-cn"

...

Since the testing pattern is "sans-serif" and the editing pattern is always inserted prior to "sans-serif" in the "prepend" mode, I see it's impossible that the number in the filename effects reversely for CIJK fonts no matter what we do use the language-specific overrides rules for them.

I guess you may be confused to the "append" mode? in the append mode, later one is used prior to the early one right:

FcConfigSubstitute test pattern any lang Equal "zh-cn"
FcConfigSubstitute test pattern any family Equal "sans-serif"
Substitute match
        pattern any lang Equal "zh-cn"

Sorry about this, I was confused by the vocabulary fontconfig uses, and had no time to double-check it again

It has already been fixed in fontpackages-devel documentation, I should have remembered to notify you

No problem. I think I had a great opportunity to see how it works :)

Anyway, fixed in knm-new-fixed-fonts-1.1-10.fc{10,11,12,13}.
