[Fontconfig] FontConfig font selection problem

[Akira TAGOH]

Please explain what the font you are expecting to see and what the
font is actually selected. it's hard to figure out what's going on

try:
$ fc-match sans-serif

or

$ fc-match sans-serif:lang=ug

perhaps. or whatever the alias font you are suspecting.
