It also comes with the framework using MyGUI to use fonts in .ttf and .otf format (I have tested and confirmed that .otf works).
What this obviously means is that it will now be significantly easier for modders to add in custom fonts, and replace the existing ones. With OpenMw 0.30.0 (have not tested with 0.31.0 yet, but I'm sure it works) I have been able to replace the default Magic Cards font with a slightly edited version of a "Magic Cards" font I downloaded online. The font was free for personal use so it should be okay to distribute.
The issue with this however, is that while I did get a very nice looking replacement for the vanilla font working in game, it does not support international characters. In fact, I have not been able to find a single variant of the Magic Cards font that supports the international characters required. I have tried Planewalker, a couple versions of Magic Cards Normal, Magic Medieval, and Goudy Medieval, and none of these support international characters, which is obviously a huge problem. I don't know what version of Magic Cards Bethesda used in Morrowind, but I have not been able to find a .ttf or .otf version of it.
So what I'm wondering is, is there some way I can get the game's .fnt files into a workable format? Any way I can convert them to a format that fontforge could open? Failing that, would it be possible for someone to get screenshots of every single character in the font? I know this would be extremely tedious and I'm not expecting anyone to be able to help me, but it would be extremely useful.
Lastly, before I commit myself to a rather large project, is there anyone already working on a replacement for Magic Cards? I remember being told someone was working on one that included international characters, but I have not heard about this since. Is it true? If not, I might be able to help. It would require me remaking/adapting a pretty large amount of characters, but I imagine the end result would be very much worth it.
Of course, if I could just find a version of Magic Cards in truetype or opentype that supported these international characters (I still have no clue what variant of Magic Cards Bethesda used), I could put it into OpenMw and be done with it, but I have not had any luck with this myself, so I'm not too optimistic about it.
Bonus: Redguard uses .fnt fonts too, and has its own typeface, unfortunately I have not been able to open these fonts at all. If anyone could help me with this, I might (at some point) create an opentype version of Redguard's font.
