unicode chars in epubs after flashing

hakim · 10-10-2009, 04:35 PM

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?

Just use the LRF format. I had bad luck with Unicode ePub on PRS-505 but it was all fine with LRF. However, I found my reader crashes much more often opening/processing LRF, so use that format with care.

EPUB uses a completely different rendering engine with a completely different approach to unicode fonts. To date there is no known way of getting unicode fonts inside EPUB without modifying each EPUB file separately (by adding special CSS rules).

Thanks for the suggestion. Finally found where to set converted file format in calibre and tried converting few books. Everything seems to be ok. No crashes even with large graphical novels and unicode chars are displayed correctly in normal books.

I see. I just wonder why calibre viewer displays EPUBs with unicode text correctly even theoretically it shouldn't.

Because the displaying device (=your computer) has unicode fonts installed and the displaying software uses them. Neither requirement is fulfilled with Sony's (Adobe's) implementation of EPUB, unfortunately.
