Hmmm.... I haven't needed to add fonts to my berry, so I can't say if there are other ways to get them easily. But if you upgrade your blackberry os, the os does come with a variety of font languages you can pick from. I can remember seeing font packs you can download without upgrading your os, but it's been awhile back and I can't remember where I saw them.
Also there might be a chance you could get them from your cell service provider and to have them add the ones you need for free. I know some cell service providers here in the US will do things like that, so it might be worth looking into.
I hope this info will help at least a little. Others here may be much more knowledgeable on this subject, and hopefully they will chime in and steer you in the right direction for a easier solution!
