      size_type copy( CharT* dest, size_type count, size_type pos = 0);
      Copia un [pos, pos+count) sottostringa di stringa di caratteri puntata da dest. Se la sottostringa richiesto dura oltre la fine della stringa, o se count == npos, la sottostringa copiato è [pos, size()). La stringa di caratteri risultante non è con terminazione null.
      Original:
      Copies a substring [pos, pos+count) to character string pointed to by dest. If the requested substring lasts past the end of the string, or if count == npos, the copied substring is [pos, size()). The resulting character string is not null-terminated.
