i can confirm it that this is UTF8 related problem with the service and not with AXIS.I was looking into an issue a coworker ran into calling the Xmethods Babelfish translation service (specifically to test out non-ascii chars), and decided to try a simple WSDL2Java based client against the service to see how it compared to how he was using AXIS (1.2RC2), and I was able to reproduce nearly the same problem.
I figured I'd ask here before digging too deep on this one - hoping that maybe someone can spot either what I'm doing wrong or what the service itself is doing wrong, or what may be a bug in 1.2RC2? I'm sure I've seen non-ascii chars work just fine in AXIS response envelopes before, so I'm not sure what's up with this one...
i have run the same test with XSUL SOAP stack using SDI and it failed in my UTF8 decoder as well.
alek
ps. here is what i got and looks like a` is incorrectly encoded as \u00e0 ? server sends Content-Type: text/xml; charset=utf-8 and xml declaration has UTF-8 si really it should have been utf8 ...

With an HTTP content type header of: Content-Type: text/xml; charset=utf-8
The AXIS Fault I'm getting back in the simple WSDL2Java generated client (unit test hand-modified to just run as a standalone client without Junit) is slightly different than what my coworker is getting, but both are the same below Message.getSOAPEnvelope in the stack, where it's trying to parse the XML for the SOAP envelope in both cases, via the DeserializationContext for the response envelope.
The encoding for the response envelope is marked UTF-8 as is the HTTP response headers associated with that envelope. The envelope looks fairly valid by eye and a simple Java program that just posted the above request to the same service and read and dumped out the response using a UTF-8 encoding didn't complain about any of the bytes in the response.
Note: I don't get the error if the response contains just ascii chars.
Here's one exception I'm getting in the standalone test (MustUnderstand checker asks for the SOAP env):
{http://xml.apache.org/axis/}stackTrace:org.xml.sax.SAXParseException: Character conversion error: "Malformed UTF-8 char -- is an XML encoding declaration missing?" (line number may be too low). at org.apache.crimson.parser.InputEntity.fatal(InputEntity.java:1100) at org.apache.crimson.parser.InputEntity.fillbuf(InputEntity.java:1072) at org.apache.crimson.parser.InputEntity.isXmlDeclOrTextDeclPrefix(InputEntity.java:914) at org.apache.crimson.parser.Parser2.maybeXmlDecl(Parser2.java:1048) at org.apache.crimson.parser.Parser2.parseInternal(Parser2.java:520) at org.apache.crimson.parser.Parser2.parse(Parser2.java:318) at org.apache.crimson.parser.XMLReaderImpl.parse(XMLReaderImpl.java:442) at javax.xml.parsers.SAXParser.parse(SAXParser.java:345) at org.apache.axis.encoding.DeserializationContext.parse(DeserializationContext.java:226) at org.apache.axis.SOAPPart.getAsSOAPEnvelope(SOAPPart.java:645) at org.apache.axis.Message.getSOAPEnvelope(Message.java:424)
And here's another another almost identical one from another batch of client code using AXIS directly (without WSDL2Java)
