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.
