I tested the software yesterday and I saw strange characters (I think that they were utf8 encodings) in the folder names of a yahoo imap account.
The folder names were in Greek

Thanks for the feedback. I will test this out and see what I can do.

Confirmed this bug and fixed it with the following commit:

github.com/jasonmunro/hm3@bb4f556344

The IMAP library has the ability to handle non-ascii folder name conversion per the RFC, we just did not have it enabled! Thanks again for the feedback.

well, the folder with greek letters displays properly in the folder list, but trying to access it causes multiple errors:

javascript errors thrown about a invalid selector
bad formatting of the folder name in the message list heading
probably more!

Re-opening this until I clean the rest of these issues up.

OK, I think this is resolved now. We had some hacky work-arounds for odd-ball folder names, but they obviously did not correctly handle a pure non-ascii value. I just pushed the following change-set that utilizes bin2hex and hex2bin to "encode" a folder name so it can be passed around safely in the UI:

github.com/jasonmunro/hm3@060a4bd2cb

This is a much more comprehensive fix than the hacky stuff I had in place before, so thanks again for the report! Any change you could re-test with the current master branch and let me know if it's working correctly?
