Probably the page you've tried it on wasn't encoded in your locale
encoding. If the page was in latin1 and your locale is UTF-8, there will
likely be invalid (for UTF-8) byte sequences in it.
For a locally stored page, the code above worked fine with tagsoup-0.6 and
tagsoup-0.10 when the page was utf-8-encoded, but if it was latin1-encoded
(and contained non-ASCII chars), it raised an
invalid argument (Invalid or incomplete multibyte or wide character)
error (on hGetContents, though, I suppose that's because I used readFile
and not th Curl-bindings).
