Which encoding is used by offlineimap?

Hi there.

I am getting the following errors:

and, while the first one I'm not able to detect where the problem is,
I think the second one is related to the file's encoding:
all the emails I have whose sender wrote using special characters
(if I open a file with vim or emacs I can see the special characters)
provide me with the same error.

My question is: could I just re-encode this emails into an encoding
offlineimap and gmail
accept always? how?

I provide more info on this at

Thanks,

Victor.
