Default sans-serif font which is used in system, doesn't have some characters from Middle-Eastern languages. So I want to set a fallback font to be used when some symbols are missing.
AFAIK, it's related to
fonts.conf files. Here is my current
<!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <alias> <family>sans</family> <prefer> <family>FONTNAME</family> </prefer> </alias> </fontconfig>
FONTNAME is the font which have all symbols. It works, but after setting this, the default font disappeared and whole system use
FONTNAME as default sans font. (Note that,
FONTNAME has latin characters too.)
