These Chinese fonts are not complete enough neither for Russian nor
for Greek.

But Qt doesn't notice because Qt only checks U+0410 for Cyrillic
and U+0390 for Greek. If U+0410 is there, Qt assumes the font
supports Cyrillic, if U+0390 is there, Qt assumes the font supports
Greek.

As Qt doesn't check any other characters and doesn't ask fontconfig
whether the fonts really supports Russian or Greek, Qt will not notice
if important characters for Greek or Russian are missing.
