definitely not.

Using a site encoding would probably be the best way (as done by e.g.
Plone and Archetypes).

Most sites use in fact a fixed encoding most of the time.
At the places where a different encoding is used, it can be
employed explicitely to convert to unicode.


As pointed out in private email ("charset negociation will not work"),
the response charset has a significant impact on the charset
used in form data sent back to the server.
This may pose severe problems when the response charset is
not the same as the site encoding (for textual form data).
