That works as a solution for people using Servlet 2.4.  I have 
production environments that aren't there yet, so I'm motivated to 
find a solution within Struts.

29668 is basically a statement of the problem I am facing.  I guess I 
should have looked through bugzilla.    It looks as though 29824 
proposes using setCharacterEncoding, so I don't think it would 
compile with Servlet 2.2.  (I haven't tried it yet.)

No; request.getCharacterEncoding still returns null, which means that 
Struts still uses a hard-coded default value.  I was noticing that in 
the nightlies of commons-fileupload, the library attempts to retrieve 
the charset from the 'part' (of the multipart/form-data) but that 
doesn't seem to be getting set either.  I haven't gotten down to the 
level of looking at what the browser sends over the wire, but I 
plugged that in and fiddled with some logging in 
CommonsMultipartRequestHandler and it didn't look as though the value 
was being sent.

Would it be a bad idea to use reflection to test the request to see 
if it accepts a setCharacterEncoding property?  It seems like this 
might provide a solution which works completely for Servlet 2.4 and 
could still give CommonsMultipartRequestHandler a place to look up a 
configured encoding for earlier versions of the Servlet API.  I'm not 
sure if that's what Martin is suggesting, or if he's just suggesting 
that we set out this way with the expectation that we'll eventually 
be able to use the same property for both kinds of form submissions...
