QSvgGenerator generates question mark "?" instead of UTF-8 characters on Windows

I'm using QSvgGenerator for generating SVG from my QGraphicsScene

I have many text items on the scene (QGraphicsTextItem), some of them are in ANSI but some of them are in Farsi language and use UTF-8 characters. when I'm on Ubuntu20.04 Linux it's working correct as expected but when the same application runs on Windows Server 2012 it's generating question mark "?" instead of each utf8 character to output file.

Thank You
