Qt Font fallback when glyph not found

[Gnomengineer]

Hello

I encountered a problem with my Qt Font setup. I'm using the NotoSans font for multiple languages including Thai and Arabic. I have multiple positions where I have a dot (FULL-STOP) symbol to be translated. Now the problem is that NotoSansThai-Regular (or the arabic one) doesn't support FULL-STOP unicode symbols which ends up in me having the "Tofu" symbol displayed.

Is there a way to tell Qt that it should use NotoSans-Regular instead of NotoSansThai-Regular whenever it doesn't find a glyph? I don't want to use another font at all and merging the font files is the last I opt to.

let me know if you need more information. As this code is restricted to be published i can't probably show more but I'll see.
