[Fontconfig] Font matching in Unicode locales

[John Alexander Thacker]

This mailing list is being very slow for me, and I'm seeing the responses
in the online archives long before I'm receiving the emails.  So I'll 
respond now anyway.

First, a problem I noticed when upgrading:  confdir.sgml.in isn't getting
added to the list of files to include in the tarball created by doing 
"make dist".  This causes compilation problems when using said tarball.  
I don't know my way around automake that well, but it seems to me that 
this solves the problem:

Thanks for the responses, and I think I have a better idea of how this all
works.  Keith Packard's suggestion of adding this to local.conf:

<!-- set desired language if unset -->
	
	<match target="pattern">
	  <test compare="eq" name="lang" qual="all" >
	   <string>unset</string>
	  </test>
	  <edit name="lang" >
	   <string>en</string>
	   <string>ja</string>
	  </edit>
	 </match>

works perfectly as expected when my locale is unset.  If I do have LANG
set to en_US.UTF-8 there's no change, of course, since fontconfig looks
for languages supporting "en," or possibly "en_US."

I haven't tried Keith's other suggestion, and I haven't been able to
get Owen Taylor's suggestion to change the behavior at all.  If I upgrade
to CVS or 2.2.90 and change Owen's suggestion from

<test compare="eq" name="lang"><string>en</string></test>
...

to

<test compare="contains" name="lang"><string>en</string></test>
...

then applications (gucharmap, gedit, etc.) start preferring to use Kochi 
Gothic and Kochi Mincho for Roman characters as well, over all the the 
English fonts that appear first in "fc-match --sort."  I don't really 
understand why, though.

I'll look into the strong binding suggestion.
