Rich editor misses usernames with umlauts

[thoka (Thomas Kalka)]

We have umlauts enabled in usernames, which works fine in markdown, but not in the new composer:

Thanks for the report. We’ll take a look!

I was able to repro after configuring the following settings:

1. configuring these settings to allow some unicode characters in usernames
   • unicode_usernames
   • allowed_unicode_username_characters (e.g. [äöüßÄÖÜẞ])
2. create a user using one of those chars in their username
3. try to mention them in a post using the new rich text editor

We should double check that mentions for group names w/ unicode characters work too when we fix this.

Just to remain that so called swedish o, å and Å, misses from that list. And yet it can be just an example, and å/Å is accepted — never tested (mostly because all Finns have learnt not to use those letters)

Thank you for reporting, unicode support has been added with this change:
