Problem to add the domain in .рф zone

[itfn]

Problem: I Try to add the domain домен.рф but it gives an error: Wrong Top Level Domain syntax: рф!
This TLD is valid in the IANA Root Zone Database http://data.iana.org/TLD/tlds-alpha-by-domain.txt as XN—P1AI
How can I fix it?

Disable TLD.

1) nano /var/www/ispcp/gui/include/input-checks.php
2) comment on the expression «/*_validates_tld($matches[3]))*/»
3) saved and added aliases without checking TLD =)

Successful administration!

Yes, it's working, but I solve it another way :
In /var/www/ispcp/gui/include/input-checks.php search for function
_validates_tld($tld) and add to $pattern line with .рф zone

PHP Code:

$pattern =
      '@^(?:
           (?:a[cdefgilmnoqrstuwxz]|aero|asia)|
              ...
              ...
              рф|  
              ...
              ([a-z]|[a-z]{7,})
       )$@ix';

Excellent! Of course this solution is better!
