I can confirm that the test fails on http without the fix and succeeds
with the fix.

Yes, I'm going to take deeper and wider look at the encoding/decoding
problem after this patch is reviewed and committed.

Having all such cases embeded in the whole test suite might make it
more complex to understand and maintain. I think it's more of a broken
design than a bug and can be fixed by explicitly setting boundaries
which would care about URI encoding (and the rest of the code would be
using decoded URIs).
