[Bug 590104] Re: ace domain format not allowed for .de nameservers

  Binary package hint: whois
  
  Hi,
  The whois client has a new feature(partially bug) (since Ubuntu 10.04), which converts domain names with special characters to the so called ace format (müller.de --> xn--mller-kva.de)
  
  The DENIC whois servers only accept domain ace's when the parameter "-T
  ace" (only in combination: "-T dn,ace" or "-T dn,st").
  
  So, now when asking for the domain name "müller.de" you get the message
  that that domain name is valid, even if its registered.
  
  As I could figure out, this problem is part of the whois since version
  4.7. I'd recommend turning off that idn2ace conversion to solve the
  problem..
  
+ I've already tested to disable the conversion by commenting out line
+ 1010,1011 and 1026,1027
+ 
+ 1010:         if (idna_to_ascii_lz(domain_start, &q, 0) != IDNA_SUCCESS)
+ 1011:            return ret;
+ 
+ 1026:         if (idna_to_ascii_lz(ret, &q, 0) != IDNA_SUCCESS)
+ 1027:            return ret;
