Transform a Unicode String to ASCII Compatible Encoding String according to the algorithm defined in RFC 3490.
If the transformation fails (because the input is not a valid IDN), an exception will be thrown.
This method can handle either an individual label or an entire domain name. In the latter case, the separators are: U+002E (full stop), U+3002 (ideographic full stop), U+FF0E (fullwidth full stop), and U+FF61 (halfwidth ideographic full stop). All of these will become U+002E (full stop) in the result.

Translates a string from ASCII Compatible Encoding (ACE) to Unicode according to the algorithm defined in RFC 3490.
Unlike toASCII, this transformation cannot fail.
