Hello, everybody. I've been using the DeDRM plugin for Calibre for years now, and it's been working a treat...up until recently. Now some of the Kindle books don't seem to process correctly when I add them to Calibre. The fonts get corrupted or something - the characters look incomplete. I'll insert a screenshot down below so that you can see what I'm talking about. I should probably mention that I have an older version of Kindle 4 PC and download books in the good old .AZW3 format and not the problematic .kfx. Has anyone else encountered this issue? Any idea how to fix it?

Did you ever figure this out?

I can't experiment right this minute.
