I don't think this is a correct inference. In http://www.w3.org/TR/REC-xml/#charsets, it says Consequently, XML processors MUST accept any character in the range specified for Char. ] Character Range [2] Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | /* any Unicode character, [#xE000-#xFFFD] | excluding the surrogate [#x10000-#x10FFFF] blocks, FFFE, and FFFF. */ but it doesn't specify that it must accept *only* characters in that range. In fact, the next paragraph states All XML processors MUST accept the UTF-8 and UTF-16 encodings of Unicode 3.1 ... In http://www.unicode.org/Public/3.1-Update/UnicodeData-3.1.0.txt, the list of Unicode 3.1 characters, the SOH character is the second entry. -- Matt http://ftbfs.org/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
