ISPConfig supports allready special chars in domain names, you just have to enter the domain name in IDN code.
You have to enter the domain in IDN encoding as I explained above, see Wikipedia: http://en.wikipedia.org/wiki/Internationalized_domain_name You can use e.g. this converter if you dont know the punicode version of your domain: http://idna-converter.com/

Now I understand, but ispconfig should convert it. Also the php included doesnt support the convert functions yet how can I use it?
PHP does not have to support a conevert function. Please visit the links that I posted above, the second link is a pnicode converter. Convert your domain name to punicode and then add this punicode in the domain field.
Php got functions for that http://php.net/manual/en/ref.intl.idn.php (PHP 5 >= 5.3.0, PECL intl >= 1.0.2, PECL idn >= 0.1) I already found a converter, but i need a function to use in php scripts.
