https://github.com/owncloud/core/blob/master/lib/private/user/manager.php#L267-L271

Only the following characters are allowed in a username: "a-z", "A-Z", "0-9", and "_.@-'"

Not sure where this gets killed, since it's really important information, but it will not work in the end anyway.

[DeepDiver1975]

We did discuss this already in #24359 - this will break badly.

Please note that the user name is more a technical identifier of a user - keep it as simple as possible.
Any fancy name can be use in the displayname. THX

[nickvergessen]

Ill reopen this, to check why the character error message is not displayed in the ui
