There is now Seaside2.6b1-pmm.65 a with an experimental WAKomEncoded
for Squeak 3.9 called WAKomEncoded39. At least your example works.

A few notes about this:
- does (should) not break any existing, working code. This includes 3.8 and 3.7.
- no changes in Squeak or Kom
- no additional code, only this additional class

Getting WAKom to work is a bit trickier. I requires hacks, you can choose where.

if Squeak:
change: #unescapePercents to use latin-1 instead of utf-8
This might break SqueakLand or SmallLand code.

if Kom:
Changes sends from #unescapePercents to
unescapePercentsWithTextEncoding: 'latin-1'
This is not at all portable to 3.8 or 3.7.

Note that these are really just hacks. You might want to use them
internally (they get the job done, for now at least) but they are no
general solution.

And this works for any encoding not just Latin-1. The
Latin1TextConverter just happens to the text converter that does not
decoding.
(Yeah, really great name)
