I don't think you can force Qt to fallback only to QRC fonts - for starters
how would Qt know which paths in your resources have the fonts?

But, you could also store a list of the fonts, and their character ranges.
When you load the texts, check each character is in one of the ranges, then
load the font using QFontDatabase.addApplicationFont.  If a previously
loaded font is no longer required, then removeApplicationFont to conserve
memory. 

Hope that helps,
