Parâmetros

Retornos

O equivalente Unicode da subcadeia de caracteres IDNA especificada pelo parâmetro ascii.

Exceções

Exemplos

O exemplo a seguir usa o GetAscii(String) método para converter uma matriz de nomes de domínio internacionalizados em Punycode. Em GetUnicode(String) seguida, o método converte o nome de domínio punycode novamente no nome de domínio original, mas substitui os separadores de rótulo originais pelo separador de rótulo padrão.
