BOOL IDNA_convert_from_ACE	(	char *	name,
		size_t *	size
	)

Convert a possibly ACE-encoded name to a name in native codepage.

Todo:

Check for over-run on output.

1) Pass through labels w/o "xn--" prefix unaltered. 2) Strip "xn--" prefix and pass to punycode_decode() 3) Repeat for all labels with "xn--" prefix. 4) Collect Unicode strings and convert to original codepage.

BOOL IDNA_convert_to_ACE	(	char *	name,
		size_t *	size
	)

Convert a possibly non-ASCII name into ACE-form.

E.g. convert "www.troms›.no" to ACE:

1) Convert each label separately; "www", "troms›" and "no" 2) "troms›" -> u+0074 u+0072 u+006F u+006D u+0073 u+00F8 3) Pass this through `punycode_encode()' which gives "troms-zua". 4) Repeat for all labels with non-ASCII letters. 5) Prepending "xn--" for each converted label gives "www.xn--troms-zua.no".

E.g. 2: "bl†b‘r.syltet›y.no" -> "xn--blbr-roah.xn--syltety-v1a.no"
