An imap log might help shed some light on this. See https://wiki.mozilla.org/MailNews:Logging

Reporter Victor,
Thanks for the log and sorry for long delay in getting back to you.
In the log it shows activity with at least two servers, gmail and yandex. Are you seeing problems only on the yandex account(s)? Are you also seeing problem with gmail account(s)?
I see that yandex does not support the UTF8=ACCEPT imap capability but gmail does. Not sure if that would cause the problem, but it's interesting.
Please check the setting of mail.server.default.allow_utf8_accept pref in config editor. It should be set to default value true. If not, set it true and restart TB and see if that helps.
If doesn't help, please paste into your response to this comment the Cyrillic/Russian character string you expect to see and I'll try to create a folder with that name using an account that does not support imap capability UTF8=ACCEPT.

Now my Russian-named folders are shown correctly.

Ok, I'll go ahead and close this as INVALID. But I'll still ask if you know what fixed it, if you know.
