in thread Converting character encodings

An XML compliant parser must support Unicode, but a particular Unicode file can be represented in ISO-8859-1.

    That's a proper subset of UTF-8, so not really necessary. Can a particular XML file be represented in, say, 8859-6 or JIS-X, and still be standard? I don't like this because it means that a file can't be read unless the parser knows that character set.

      7-bit ISO-8859-1 (also called "ASCII" {grin}) is a proper subset of UTF-8, but not 8-bit ISO-8859-1. So yes, you'd need to declare the file as ISO-8859-1 if you wanted to have any "second half" characters, but otherwise you can let it default to UTF-8.

        Oh yea, that's right. 8859-1 is a subset of Unicode character encoding, but not UTF-8. I mixed them up.

        So one can find existing xml files with various encodings? Does that mean a parser needs a conformance statement as to what encodings it can understand?
