textile-double-escape-bug.t: tolerate any valid encoding

Discount in current Debian unstable turns the IURI href into a URI
by encoding the Unicode as UTF-8 and %-escaping each byte.
That is valid, and matches Wikipedia's expectations, but was breaking
this test for me.

It would also be entirely valid (and lead to equivalent parsing) if the
ö was represented as ö, ö or &#xf6 in the text and/or the href.
