Well, I suppose that depends on how you write your application. 
Bricolage, for example, is written in such a way that it expects 
request parameters to all be in the same character set. So to decode 
them all would be simple (and very cool).

Yes, it would be cool and proper to have Apache::Request do UTF-8 
conversion, which I think a subclass would easily be able to do.

I think that we're all in agreement that perl variable flags should be 
preserved where the underlying code is designed to handle Perl data 
(such as pnote()), not just character data (as with APR::Table).

I think that this may not be possible given what you submit to the 
browser and get back from the browser is not Perl data (e.g., params). 
But pnotes(), for example, should do the right thing.
