[Fontconfig] Font priority and locale settings

[Akira TAGOH]

Yes, it is the expected behavior. the locale settings affects to FC_LANG
property. you have two options to change this:

1) add a lang property to query. which is most common way and most
applications does.
    e.g. fc-match serif:lang=en

2) if you don't like 1) because it still affects the order of the whole
list say, set FC_LANG env var to change the default language regardless of
current locale.
    e.g. FC_LANG=en fc-match serif
