How to Output Query Result as UTF-16 XML

[Bill Wordsworth]

This is what I have done so far:

In Stored Procedure, I set-
* v_xml OUT NVARCHAR2
* v_xml := '<?xml version="1.0" encoding="UTF-16" ?>...'; -- without
any chr(10) newline

In Application, I set-
* header('Content-Type: application/xml; charset=UTF-16');
* mb_convert_encoding($v_xml, "UTF-16");

However, my data fetch keeps throwing parse error in IE/Firefox. And I
keep getting my data as ASCII (mb_detect_encoding($v_xml)), not
UTF-16?

According to http://www.oracle.com/technology/tec...faq.html#nchar,
"there is no NCHAR or NCLOB support in the OCI8 extension." And
http://www.oracle.com/technology/tec...cle-manual.pdf
makes no mention of UTF-16.

I am not sure how to get UTF-16 XML (or, how to make character set to
SQLCS_NCHAR if that would help)?
Cheers, Bill
