Unicode decode error

I am trying to convert an Amazon *.azw file. After running for a while I get the following error message:

Unicode decode error: 'utf8' codec can't decode byte 0x8b in position 674: unexpected code byte.

That sounds to me as if the file has no DRM protection, but rather it is a conversion error only. Any solution? I am using the latest calibre version, 0.6.15.

Python 3 wouldn't help with this. This error involves the decoding of the files contents. In python 3 they would simply be the bytes data type and would still need to be decoded.

Don't these UnicodeDecode errors usually result from encoding conversion or encoding mixing? All such errors disappeared in pacify when I switched to Python 3.

No The largest source of Unicode errors are typically files that either don't declare their encoding (calibre uses the chardet library to try to guess it in this case) or files that declare an incorrect encoding/have corrupted data (which is what I suspect in this case).

Ok... true enough, that wouldn't be address by Python 3.

That was the complete error message. Title of the pop-up window is ERROR: ERROR: Unhandled exception.

Kovid, I'm opening an old thread. I got similar error when trying to convert from epub to mobi (or lrf).
I'm using 0.6.26 on windows 7. Is this something that can be fixed in calibre or it's a local error?

Thanks in advance.

that's a different error. hard to say more without looking at the file in question.

I'd like to share the book with you, but it's a large file, 18Mb. I guess too big for email?

It's one of my liberated epub books from Sony, wanted to convert for Kindle.


EDIT: gmail says the max size is 25Mb. Is there a way I can email it to you Kovid?
