The Brazilian ccTLD comes into the dancing of IDNs . It permits that Registrants register names that have stressed characters of the Portuguese language: à, á, ã , â, é, ê, í, ó, ô, õ, ú, ü and ç. However, attention! because if you can register a name with these characters, it will be necessary, imperatively, you have been registered before an identical name in ASCII characters. For example, for registering «verão», it will be necessary get previously the «verão» version without stress.
