Reading Greek, Syriac and Aramaic on a Pocket PC

I am quite sure that the number of people who have a deep desire to be able to read ancient languages on their Pocket PC is small indeed. But the fact that texts that should work are available online might lead one to hope. Yet most of the texts I’ve tried confront major issues. Aramaic and Syriac texts for Pocket e-Sword simply can’t be opened. Greek text files of Josephus and Philo show accented letters as little boxes. Is the problem with my rather antiquated little iPaq? Or is it simply that so few people actually try to use these files that no one has noticed the bugs, or if they’ve noticed, no one has dealt with them?

I’ve tried several different programs – Gramcord’s Olive Tree software, Pocket e-Sword, Hebrew Reader, Mobipocket reader. But there are still some files that don’t open at all, or don’t open as anything readable, in any of the programs I’ve tried.

Suggestions, remedies, and alternatives are welcome!
