It is also not appropriate for the forms case, because there
is usually no alternate encodings to choose from.

But it is not too difficult to see how this can be improved.

The user does not understand character encodings, but the
user understands characters, in particular the ones s/he
typed. So it should not be too difficult to pop up a warning
saying (taking US-ASCII and my name, in HTML entities
written D&uuml;rst, as an example):

--------
Sorry, this form cannot handle some of the characters you
just typed. The data will be sent as "D?rst".
      [OK to send]   [Let me change it]
--------

Speaking from personal experience, I would highly prefer
such a message (and the chance to change to "Duerst",
my official fallback) rather than to send garbage to
the server. I also think that the above is not too
difficult to understand for the user, because it is
expressed in terms familiar to the user. Of course,
I'm too much of an expert to be able to judge this,
but you should at least give it a try.


Regards,     Martin.
