echo "0L/QsNC/Cg==" | base64 -d

Third letters which cause this problem:

(UTF-8: 0xD0 0xBF)

(UTF-8: 0xD1 0xBF)

(UTF-8: 0xD2 0xBF)

If such a folder (three Cyrillic letters, the third one a "special" one) is created in the filesystem directly, it is displayed by SOGo with the third letter replaced with:

(UTF-8: 0xD3 0xBF)

This could also be observed when a Russian folder "Sent" ("????????????") was created in the filesystem directly (after an import). Then its 3rd letter was exactly a bad one, so it was displayed incorrectly in SOGo.

Either 0xbf or the last 2 bits set (3 == 11B) in UCS seem to be the trigger.

Every third Cyrillic letter is affected: I've just created (in the filesystem) a folder with a very long name consisting solely of Cyrillic small PE, and this is how it is shown in SOGo web-interface:


* denotes the bad sign here, _ -- the good letter.

I wonder whether other interfaces have this problem. (What other interaces does SOGo server except for the web-interface?.. Well, probably, only ActiveSync. IMAP is done directly through dovecot, and dovecot treats them fine, was confirmed by an experiment)

The patch has been submitted as a pull request at github.

The same problem must also be a part of [^] .

Perhaps, it was left unnoticed because in practice it appears only in the rare case when there is a non-Latin two-byte Unicode character which has all last 6 bits "1" at the third position in a folder name.
