- Decrypt encrypted/obfuscated font files.
Recently, it's come up in the
EpubSplit thread that encrypted font files weren't being handled gracefully.
It turns out Calibre Convert has been 'preserving font encryption' for nearly
15 years.
This version of EpubMerge decrypts the font files, but it doesn't make any attempt to re-encrypt them again in the merged epub. I just don't see the point.
There are, in fact, two different 'encryptions' used, according to the Calibre code. I've carried over the implementation for both, but I only have one to test with. FYI.
