Just edit the lang field in the pattern.
But how do you set lang field to be exactly the current value of your
LANG/FC_LANG variable? I think the point is to make it dynamic rather
than a static value written to a local file.
LANG (as opposed to FC_LANG) *is* already used to provide a default
value dynamically, provided programs use FcDefaultSubstitute which I
think they all do.
(BTW- Akira- is there a special reason why applying the new string set
needed to be done in FcConfigSubstituteWithPat in addition to
FcDefaultSubstitute?)
In case you need a different configuration for individual programs and
cannot modify LANG for those, i. e. as would be possible through
FC_LANG, I suspect you could create a file like:
<fontconfig>
<include>/etc/fonts/fonts.conf</include>
<match target="pattern">
<test name="lang" qual="all" compare="not_eq">
<string>ja</string>
</test>
<edit name="lang" mode="prepend">
<string>ja</string>
<string>zh-cn</string>
</edit>
</match>
</fontconfig>
(i. e., assigning 'ja','zh-cn' to 'lang' in case no 'lang' was in the
pattern (unlikely) or 'ja' was not in it)
and use:
FONTCONFIG_FILE=your.config.file fc-match
because that will redirect fontconfig configuration for that single
operation to your file. It would mean you need to have as many of those
configuration files as you would have possible settings of your FC_LANG
variable that are not matched by settings of the LANG variable (are they
that many..??)
