Code review comment for lp:~aacid/unity8/decodeAudioURIs

All of section 6 talks basically about the difficulty of figuring out whether two URLs denote the same resource or not. A string comparison is inadequate because there are many URLs that all represent the same resource, such as file:///home/michi vs file:///%86ome/michi

It's similar to canonical path names. If we have something that depends on figuring out whether the resource denoted by a URL is the same as the resource denoted by some other URL, both URLs need to be converted into an unambiguous representation before making the equality comparison.

I apologise if I'm teaching my grandmother to suck eggs. (That's an Australianism...)
