A font file contains multiple languages, problems not arise. When multiple font files are referenced at the same textblock run, problems arise.

Could you bring the Text to geometry and draw the geometry with LinearGradientBrush?

How to bring the Text to geometry see https://stackoverflow.com/q/1036327/6116637
