If you have anything that > calls itself an XML parser it must be able to read utf-16. XML does NOT support UTF-16 since UTF-16 includes the surrogates - that is in fact what *distinguishes* it from UCS-2. That the XML 1.0 spec ('scuse me, 'Recommendation') *says* that it requires support for UTF-16 is in fact an error in the text since it explicitly forbids surrogates (aka UTF-16) in the allowed char range spec. It is like saying 'We require Japanese support, except you can't use *any* Japanese.' It's a nonsense statement. "Character Range [2] Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */ The mechanism for encoding character code points into bit patterns may vary from entity to entity. All XML processors must accept the UTF-8 and UTF-16 encodings of 10646; ^ | The Error. What it actually requires is a specifified subset of UTF-8 and UCS-2 encodings. -- Benjamin Franz "Real programmers can write assembly code in any language." -- Larry Wall XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
