Thanks both for your suggestions, I tried them all but nothing worked. The good thing is, I think I've found the problem - but unfortunately not the solution. It appears that it's not just Chinese fonts I can't read, it's all fonts other than the default!
My device doesn't seem to detect anything I've dropped into the system\fonts folder. Weird thing is I can't find the default font file anywhere either, and I'm displaying hidden files as well. When I'm in FBReader config and I select the Font option (which says default,25), I get taken out of the book and back to my bookshelf.
I have a feeling the solution is going to be something quite basic but I can't figure it out just now
