<a href="http://code.google.com/apis/safebrowsing/developers_guide_v2.html#Canonicalization">http://code.google.com/apis/safebrowsing/developers_guide_v2.html#Canonicalization</a> lists some interesting cases we've come across on the anti-phishing team in Google. To the extent you're concerned with / interested in canonicalizaiton, it may be worth taking a look at (not to suggest you follow that in determining how to parse/canonicalize URLs, but rather to make sure that you have some "correct" way of handling the listed URLs).<div>

Is that URLs as values of attributes in HTML or is that URLs as pasted<br>
into the address bar? I believe their processing differs...<br>

It certainly does in Firefox (the latter have a lot more fixup done to them, and there are also differences in terms of how character encodings are handled).<br>
<br>
I would be particularly interested in data on this last, across different browsers, operating systems, and locales... There seem to be servers out there expecting their URIs in UTF-8 and others expecting them in ISO-8859-1, and it's not clear to me how to make things work with them all.<br>
