|Subject:||conversion of domain name xn--zcaa.de|
the conversion of the IDN domain name "xn--zcaa.de" to unicode is broken: The expected result would be "ßß.de". But using the domain_to_unicode() method a wrongly encoded string is returned. The issue only appears if the domain name only contains "ß" characters. If the domain name also contains other characters the returned unicode string is correct.
