I recently installed Linux Mint 16 and for some reason Uyghur script won't display properly on Mozilla Firefox. For example, my recent Facebook status appears as such:http://i40.tinypic.com/2gy39mc.png
Note how the font for some letters are different than the standard font, as well as the fact that the letters aren't joined as they're supposed to be.
This same text in LibreOffice Writer shows up fine (i.e. the correct way it should), however:http://i39.tinypic.com/23vx2zr.png
The first text is from a UKIJ (Uyghur font) I downloaded via the Software Manager, while the second line below is using this font called "Aboriginal Sans" since I couldn't find any font called Sans Serif or Serif on LibreOffice Writer. I included this second line to show that even not using a specialized UKIJ font, Uyghur should still display properly.
I'm not sure why it doesn't display properly on Mozilla Firefox. I tried changing the default font to UKIJ and even then the same problem happens. Even fonts such as Burmese or Amharic show up properly, so I don't know if this is a Unicode related problem or not (it might be, though -- I see squares sometimes for some characters, but not for these languages). What's going on here and how can I solve this?
I'd appreciate any help!
