[Debian-in-workers] Bug#441319: Mitra Mono also has a similar problem

Mitra Mono also has a similar problem
Mitra Mono,\\u09ae\\u09bf\\u09a4\\u09cd\\u09b0:style=Regular

reported as a bug with fontconfig, but nonetheless putting literal
characters in the font would be a good idea for compatibility.
