Force Qt Creator to use imported fonts and enable font chain

Boopathy

Hi,
I'm developing an application which uses multiple languages from arabic, russian, latin english, chinese, japanese and korean. Currently developing in Windows to be deployed to embedded devices. I could not find an option in Qt Creator to disable taking font glyphs from windows OS.

How to disable that and force Qt creator use the fonts which i have imported?
How to create a font chain?
like eg: if i have a chinese text, first application should search for it in the first font, if not found move to next and so on until it finds the exact font and renders it.
