Cherrytree: Bug: Passwords cannot contain common characters

[chadfurman]

When trying to save a notebook in XML form with a password, I get an error that special characters are not allowed. There's no _good_ reason for this. Python supports unicode, it also supports base64, and really they're just ascii characters anyways so why can't I use common characters?

Was just about to post the same question, then found this. Always puzzles me why sites/tools don't allow strong passwords.

All characters will be allowed in upcoming Gtkmm3 version
