Subject: [idn] Error in IDN eamples for testing

One of our engineers took a look at the IDN samples for testing, and found a
problem in the data. Apparently some of the UTF-8 is illegal (using 2
three-byte sequences for a supplementary character).

Hi Mark,
The following are the offending members of structure in Appendix A of
draft-josefsson-idn-test-vectors. The data claiming to be UTF-8 is actually
CESU-8.

struct stringprep
{
char *comment;
char *in;
char *out;
char *profile;
int flags;
int rc;
}
strprep[] =
{
..........
{
"Surrogate code U+DF42",
"\xED\xBD\x82", NULL, "Nameprep", 0,
STRINGPREP_CONTAINS_PROHIBITED
},
...........
{
"Larger test (shrinking)",
"X\xC2\xAD\xC3\xDF\xC4\xB0\xE2\x84\xA1\x6a\xcc\x8c\xc2\xa0\xc2"
"\xaa\xce\xb0\xe2\x80\x80", "xssi\xcc\x87""tel\xc7\xb0 a\xce\xb0 ",
"Nameprep"
},
{
"Larger test (expanding)",
"X\xC3\xDF\xe3\x8c\x96\xC4\xB0\xE2\x84\xA1\xE2\x92\x9F\xE3\x8c\x80",
"xss\xe3\x82\xad\xe3\x83\xad\xe3\x83\xa1\xe3\x83\xbc\xe3\x83\x88"
"\xe3\x83\xab""i\xcc\x87""tel\x28""d\x29\xe3\x82\xa2\xe3\x83\x91"
"\xe3\x83\xbc\xe3\x83\x88"
},
}
...

For companies like Ben & Jerry's, Bang & Olufsen, Nestlé, L'Oreal, Kookaï,
etc. the IDN will be much more significant than the introduction of .biz and
.info. Let's make it significant in a positive sense, rather than a
significant new anti-cybersquatting expenditure.

Yours Sincerely,
