[Seaside-dev] Encoding issues? Entering 'euro sign' into a text
input breaks render

So what am I to use instead? I've not seen anything about an alternative.
I used SeasideInstaller - I always did, yet it left me with what I have
been having trouble with today - the encoding test failing, and Seaside
rendering breaking on any "special" character. I only installed other
versions of KomHttpServer in a bid to try and fix this problem.
