Glen Mazza commented on CXF-3395:
---------------------------------

Benson:  Glen, no he does not need to escape anything. StaX will escape as 
needed, unless something very funny is going on.

As I understood the developer's question per his example, he wanted to directly 
insert Chinese characters within his Java code, and CXF wasn't working under 
those circumstances.  The handful of times I had seen Asian character sets 
within Java code (or within messages properties files), the characters were 
escaped as I had shown, and I suggested that that might be a solution for him.

To me, StAX/DOM/SAX is only an issue once we are sure the Java runtime has 
happily accepted the hardcoded Chinese characters in the string constant--it 
did not appear to me that the user was at that level at the time of posting his 
question.

> hi cxf team:
>    i use cxf2.3.3 in my project,and i tansfer the hashmap through cxf client 
> to server(i use the example of apache-cxf-2.3.2,the java_first_jaxws project 
> in official promulgate package) .firstly it run normally,but when i put some 
> chinese word(not englist word) to hashmap
>    i modify the HelloWorldImpl.java(the official example project 
> file,java_first_jaxws is the project name) function just like this:
>     HelloWorldImpl.java
>     public Map<Integer, User> getUsers() {
>       Map<Integer, User> usersForMap = new LinkedHashMap<Integer, User>();
>       //汉字bug 中文 bug
>       usersForMap.put(1,  new UserImpl("yhb汉字bug"));  //-->when total english 
> word,it run ok,when some chinese word here the cxf tell error to me. 
>       usersForMap.put(2,  new UserImpl("wybl"));
>         System.out.println("getUsers called");
>         return usersForMap;
>     }
>    
>    it' seem the marshal and unmarshal crash and tell fllow error(englisth 
> word in hashmap seem runs ok):
