I have just posted an draft version of an eBook for learning some rudiments of the Cherokee Language. As Cherokee has its own writing system with a different unicode range, I had such fun with fonts and css.
My testing file can be had from:

I would like to have it tested on lots of other ePub capable readers for those who are willing.
