I have flashed my reader using
igor's flasher to add unicode support and I am using calibre 0.5.9 to convert and transfer ebooks. Now, after the flashing, filenames (when listing them) and pdf file text seem to be displayed correctly, but in epubs (created with calibre) "?" are still displayed instead of some characters. When viewing the epubs with calibre viewer everything's ok. And yes, I tried deleting and resending the epubs. Any suggestions?
