Issue conversion CBR to PDF

[poco06]

Hello,
I have been using Calibre for long time to convert CBR into PDF and have some issues now.
From time to time (let say 30%), I'm facing this error :
UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal

I have upgraded with the latest Calibre version without succes

Any idea how to move forward ?
Thanks
Pat

That's not an actual error, just a harmless warning and can be ignored. Any actual error will be at the bottom of the log, not the top.

THat indicates the CBR file in question is corrupted. Can you open it using winrar?

[poco06]

Hello,

Yes, I can open it with Winrar or any CBR viewer (like Sumatra for example).
Regards
Pat

Then open a bug report and attch the file or simply use winrar to convert it to a cbz.
