Checks whether the IDN formatted domain name is valid.
Syntax
public static function idn_domain ($idn_dom_name)
Parameters
idn_dom_name
A string value that specifies the domain name in IDN format.
Returns
A boolean set to true if the domain name is well-formatted, false otherwise.
Remarks
This function is a particular case of pm_Checker::domain, except it converts the passed in domain name to the ASCII format first.
A valid domain name shouldn't be longer than 245 characters, shouldn't be 'localhost.rev' or ending with '.in-addr.arpa' (reverse resolution from an IP address to the fully qualified domain address). IP addresses are also disallowed.
A valid domain name specified in the idn_dom_name parameter should be formatted as a series of labels glued with '.' (dot) characters, i.e. <label>[.<label>[…]], each label up to 63 characters long, beginning with a Latin letter and composed of Latin letters (A-Z, a-z), digits (0-9) and '-' (hyphen) characters. E.g. Plesk-8.main-support.support.com.
