toASCII :: Flags -> Text -> Either Error ByteString Source

Convert a Unicode domain name to an ASCII ByteString. The domain name may contain several labels, separated by periods.

toASCII never alters a sequence of code points that are all in the ASCII range to begin with (although it could fail). Applying toASCII multiple times gives the same result as applying it once.

toUnicode :: Flags -> ByteString -> Text Source

Convert a possibly ACE-encoded domain name to Unicode. The domain name may contain several labels, separated by dots.

Aside from memory allocation failure, toUnicode always succeeds. If the input cannot be decoded, it is returned unchanged.
