We need to allow the German umlauts for the user to enter as part of user name. While we add
^[A-Za-z0-9äöüÄÖÜß-.]+(?:[._-][A-Za-z0-9äöüÄÖÜß-.]+)*$
This is not working as expected and we just get an error as "Facing Technical difficulty"

I think that your regular expression is not correct. "-" sign in regular expressions is used to match any from range of characters. e.g.: A-Z or a-z. You have range that is not closed: ß- I removed "-" sign and it started to work for me.
^[A-Za-z0-9äöüÄÖÜß.]+(?:[._-][A-Za-z0-9äöüÄÖÜß.]+)*$
Update following comment of @Marek Musielak. It seems that under -. @PVM have meant either . or - characters. In regular expression these characters should be escaped:
^[A-Za-z0-9äöüÄÖÜß\-\.]+(?:[._-][A-Za-z0-9äöüÄÖÜß\-\.]+)*$

So there should be
\`character before-, right?-should not be removed? – Marek Musielak Nov 14 '17 at 10:57 -
Yes, if @PVM wants to use '-' character then it should be escaped "\-". I was not sure, why this symbol was added, but it definitely causes issue – Anton Nov 14 '17 at 11:31

/^[ A-Za-z\-_.\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u00FF.~\\-]*$/
Please try to use this one.
