Hi Kartu,
Thank you for you hints. But I still could not get my 600 to display book title etc Chinese correctly (epub files are working good so far with the css way).
What I used were three modified fonts in /DATA/fonts, with the font and file names all adapted, like tt0003m_.ttf and Swiss721 BT, etc.
(by the way, they are 3.5 MB each for tt0003m_ and tt001m_, so I wonder the possibility to fit them into the source, if power consumption is too terrible to use a large font)
I then put the prsp.sh with the "mount --bind /DATA/fonts /opt/sony/ebook/FONT" line into /database/system/PRSPlus/ , but the book titles in book list and history are still messed up...
wondering if I missed any step...
Looking forward to your reply..
Thank you.
