Hostname.toUnicode

Converts @hostname to its canonical presentation form; a UTF-8 string in Unicode normalization form C, containing no uppercase letters, no forbidden characters, and no ASCII-encoded segments, and not ending with a trailing dot.

Of course if @hostname is not an internationalized hostname, then the canonical presentation form will be entirely ASCII.
