Oh, forgot to mention, you're right.

These functions should only be used on individual path segments and the individual query string, not on the URI in its entire!

Note that there is no real specification describing how to use unicode paths and query strings. Luckily most browser act the same, but, as far as I can remember, clients are free to come up with different encodings.
