ey there:
The Tor Browser devs are working on the fonts that are shipped with Tor Browser[1].
The way the Tor Browser deals with fonts is different from other browsers, because it uses its own set of fonts and does not use the fonts on your system. This is because the set of fonts of each system could be use to deanonymize different Tor Browser users, so all Tor Browsers have the same set of fonts.
If your language has an alphabet with non-Latin letters, it would be great that you test Tor Browser Alpha at https://www.torproject.org/download/alpha/ to see if the fonts are displayed correctly.
If you see fonts not well displayed, or other related issues, you can send any comments to my email or also reply to this message.

Thanks in advance!
