Kindly Solve this UTF-16 problem

[Subhasis Sanyal <Su...@catsglobal.co.in>]

> Hi,
>     We have been trying hard to create a UTF-16 xml document. We have
> tried the following code:
> As you can see, we have tried to set a feature to allow java-encoding, but
> it is not working. The command line argument to the 
> program is a xml filename.We are creating a Unicode format xml, with the
> encoding header set to UTF-16, and sending it to the
> program. We are using the docToStr() function function to print the
> convert the document object to a string, and display it on the
> command prompt. However, the printed output shows the encoding to be:
> UTF-8.
> 
> Can you help on this issue? Is it a problem in the DOMParser itself, or
> the Transform API (in the  docToStr() function is printing this 
> wrong?) We have also tried the
> org.apache.xerces.jaxp.DocumentBuilderFactoryImpl class for XML parsing,
> and that is also giving us the same result.
