Java 1.1's mappings only support "UTF8", not "UTF-8" as a codepage identifier. This value 
is not used in output anywhere. The Content-Type is set to "UTF-8" correctly.

You're right, the client side doesn't do UTF-8. My own patched version of Apache-SOAP, in 
which I implemented codepage support around the same time as the base project, does 
do this. It also supports all other Mime types, both on the client and the server side. I'm 
considerably out of sync with the main project, though, and my code has some 
dependencies which should be eliminated first (wish I had the time).
Specifically, I use JavaMail's javax.mail.internet.MimeUtility's javaCharset() and 
mimeCharset() to convert from mime character set identifiers to java codepage ids. It 
comes with a mapping table to take care of the UTF-8 <-> UTF8 etc issue.
