The string with accented utf8 characters is a U-Label. You have to translate it to an A-Label (also called punycode) which is a string starting with "xn--" and followed by only valis DNS valid characters (English letters, digits and hyphens). 

You can check how it works on (just found it googling). 

Fred will accept (which is the punycode for á

I guess there are idn libraries for most languages so you can translate back and forth.

What exactly are the requirements? 

Well, our board really wants to allow people to register names with faroese accidentals - described previously.
  The customer problem is, that while some names like á work perfectly for our customers, names like joensen.á do not, because of the 'á'.
  The ultimative test would be an acceptance of registering the name 'áýúíóæøåðÁÝÚÍÓÆØÅÐ.fo'. This is to be understood as a string of UTF8 chars, which is equivalent to any upper/lower case combination of the same UTF8 chars.
  In our case, any other non-ASCII chars of UTF8 should be rejected .... I suppose that we as a ccTLD are authorized to decide on which chars are acceptable :-)
  A short explanation might be that we need to expand the ASCII characters just a few bits, pr. ccTLD.
