The "tests" I wrote always fail in order to output the result of the
function to the console for comparison by hand. ICU_ESCAPE is clearly
not meant to be used with InternetCanonicalizeUrl, so I'm not sure a
test for it is necessary. That said, if you would like me to include a
few tests in the patch, let me know.
