We have had a user have some fun with Unicode characters that move out of the actual text area -> Link. When trying to rename the user to a "normal" name there is only a [99e16bb96fedb23f92af27ed] 2018-06-11 20:34:51: Fataler Ausnahmefehler des Typs „Error“ (Fatal Error of Type "Error"). Getting rid of the user also does not work with Extension:UserMerge.
