I'm somehow strangely attracted to this issue, and have posted a bit
of a code review.

Well, it's an API change, and those are impossible after beta3 is
released (or at least have to wait for 3.1).

The wikipedia use of urlencoded UTF-8 (and other examples) suggest
that whether we like it or not the trend is towards this. I'd like to
support such usage rather than fight it (standards or no standards).

It could be a small enough new feature. Also note that for urls that
only use ASCII there is no behavior change. (And certainly this *is*
an important use case, e.g. to encode occurrences of + or & in query
