            Description

            I don't know why people are using URLs containing umlauts, but they're doing it more and more. Plus modern browsers don't shown the decrypted URL in the address bar any more. Problem: CiviCRM doesn't accept umlauts in URLs or e-mail-addresses.

            Resolution 1: deactivate valdation
            Resolution 2: decrypt umlauts (vaihingen-ös.de => xn--vaihingen-s-0fb.de)

                  This was touched on in CRM-16531 - so there are a couple of comments in there for anyone who wants to take on this issue.

                  The main issue is the PHP validation function being used doesn't accept non-ascii characters as valid input, FILTER_VALIDATE_URL: http://php.net/manual/en/filter.filters.validate.php . I imagine this is therefore true for email addresses as well.

                  There is a patch already accepted in CRM-16313 - if you're seeing this behaviour with that fix applied, please update the issue?

                  People have been using IDN already a few years (since 2011), that's why we're seeing them using it
