It's not quite as straightforward as always using UTF-8, unfortunately
(actually there basically isn't a *right* answer that is guaranteed to work
everywhere). But if you are using UTF-8 as your page encoding you should be
using it to encode URLs before percent escaping. WAUrlEncoder in 2.9 does
this but it looks like the one in 2.8 doesn't.

There has been a bunch of discussion about encodings on the development list
in the past few weeks. Encodings + the web = a mess, really. :)
