Youenn,

I'm updating the expected results, but there are still a few questionable
items which I believe are errors on your end, which affect all three test
cases.

1) The character #xA3 doesn't seem to be encoded correctly.  Per the rules
in the IRI spec, UTF-8 encoding for characters up to #x7f is trivial, but
for characters over #x80 it gets more complicated.  That's why included a
character over #x80 ;-).  My read is that #xA3 gets percent-escaped
according to these rules as %C2%A3.

2) There is an extra ?, encoded as %3F, following the "path" parameter.
There isn't supposed to be one in the test data.

3) You also encode "=" even though there isn't a MUST or SHOULD requirement
in the spec to do so.  You conform, but it means I'll have to adjust the
expected value in the test suite to represent the MUSTs + the SHOULDs + "=".
I'm happy enough to do that, but just thought I'd point it out in case you
think there's an erratum there.
