DeDRM 10.0.9 "string argument should contain only ASCII characters" error #481

Closed spicyllamas closed 8 months ago

Question / bug report

I'm using DeDRM 10.0.9 on Calibre 7.2 alongside the DeACSM plugin. When I try to import an ACSM from Adobe's sample library, DeDRM is producing the "string argument should contain only ASCII characters" error. I also tried deleting the saved Adobe key from DeDRM's customization and re-adding the book.

Which version of Calibre are you running?

7.2

Which version of the DeDRM plugin are you running?

v10.0.9

If applicable, which version of the Kindle software are you running?

No response

I haven't used DeACSM myself. But I believe I've seen someone mention a workaround of saving the key from the ACSM Input plugin and manually importing it into the DeDRM plugin.

Oh, yeah deleting the auto-imported one and importing it myself worked. Thank you!

Thanks for confirming that worked.
