Dear customers!
Registration of emoji in domains is now available in .PP.UA, .CO.UA and .BIZ.UA.
In addition to emoji, domains can use digits, hyphens, and Latin or Cyrillic letters (without mixing alphabets).
The list of available emoji can be viewed in the Unicode 11.0 table, excluding zero width joiner characters (200D and FE0F).
The full list of emoji can be viewed on this site.
An example of registering such a domain can be seen at i♥️.biz.ua.
