Hello

when I use name in chinese, the system said:
The user name contains invalid characters

Yes, because the regular expression detects "control characters".

EDIT: We will fix this issue within the next release.

I wanted to warn you of the postings of the user pl in in your thread in the SelfHTML-Forum, but since you merged your PR meanwhile, the warning is to late and groundless.

Thank you.

Tschö, Auge
