I thought of that... so I didn't switch the italic (as there is no italic in Japanese, anyway.) But I need the BOLD because Gmail makes new e-mails show up in boldface... so they'll end up all garbled if I don't replace the __Bold.ttf file as well.
I found
fontforge as a possible program to try -- seems to work cross platform. I copy-pasted the Boldface english characters to the CJK file, but I haven't had time to test them out yet...
I wonder if I can snag a bold.ttf file from my laptop and use that -- is there special requirements of ttf files for them to work on the Kindle?
Thanks for all your hard work and for taking time to write back.
Cheers,
Jeffrey
