Daniel Kulp commented on CXF-1771:
----------------------------------
Nothing we can do here. Those control characters are illegal in XML. See
Benson's blog entry about it:

> WstxUnexpectedCharException when returning a String from a CXF SOAP service
> containing specific characters (used with CXF client)
> ---------------------------------------------------------------------------------------------------------------------------------
>
> Key: CXF-1771
> URL: https://issues.apache.org/jira/browse/CXF-1771
> Project: CXF
> Issue Type: Bug
> Affects Versions: 2.1.2
> Reporter: Martijn Brinkers
>
> If my SOAP service returns a String that contains control characters and the
> service is consumed by a CXF client a
> com.ctc.wstx.exc.WstxUnexpectedCharException is being thrown.
> It's easy to duplicate (in my setup) by modifying one line of the CXF 2.1.2
> sample samples/java_first_jaxws:
> public String sayHiToUser(User user) {
> System.out.println("sayHiToUser called");
> users.put(users.size() + 1, user);
> return "Hello " + user.getName() + '\27'; <<<===== add
> '\27' to the String being returned
> }
> Now when you start the client sample the following exception is being thrown:
> INFO: Interceptor has thrown exception, unwinding now
