Re: Is #x81 is invalid char in xml 1.0

Does anybody have any clue why MSXML parser failed to > load this document? Your XML file has no encoding declaration, so we can expect that MS-XML will attempt to interpret the file as UTF-8. In Unicode, there is no character 0x81 that corresponds to a printing character such as something that looks like "a". In the UTF-8 encoding, there is also no code sequence consisting only of a solitary byte > 0x7F: they must always be paired or three-in-a-row. Therefore your document does not seem to be encoding in UTF-8, and MSXML is correct in rejecting it. It is difficult to figure out what encoding you in fact have: many Macintosh character sets use 0x81 for variants on A and some Windows code pages use it for u umlaut. The other common encoding that uses the code point 0x81 are recent Windows encodings, which use it for the Euro sign. Because that is the only character that doesn't use a numeric character reference, and because the characters you use there are a pretty strange collection, I think you may be trying to add some binary data, using the character range above 0x7F. If you are doing that, then you cannot use UTF-8 encoding, and you should try ISO-8859-1 (and even then, some parsers may legitimately reject if for reasons we needn't go into.) If you are not doing this, and you are trying to send some natural language, then you certainly need to specify the encoding that you are using: which language is it? Cheers Rick Jelliffe
