This is easily done; just ensure that the server always sends the same charset that the XML encoding declaration specifies. > But there's the snag: in text/xml documents, a missing charset parameter > does not mean "Charset unspecified"; it means "Charset specified > as US-ASCII". This is correct, the RFC does say that. Note that, this thread is primarily about whether the RFC *should* say that or *should* say something different, something which does not needlessly contradict the XML 1.0 Recommendation. > There is no way to fail to specify a charset in > text/* documents, and rightly so, because text without a charset > is uninterpretable. This is disingeneous; both clauses are true, but the second one implies that there is no other method of conveying the information, which, clearly, there is. So a) There is no way to fail to specify a charset in text/* documents But it does not have to be explicit. It can be implied. good way of formalising that implication would be to refer to the rules in the XML 1.0 Recommendation. b) text without a charset is uninterpretable. Also true, but that labelling is already defined in XML and handily trravels with the document instance so that it is not lost as soon as the document is saved to disk. > In SGML terms, omitting the charset in text/* documents is a mere > minimization, whereas in application/* documents it is a true #IMPLIED. Actually, if you read the XML Recommendation, then unless the charset is UTF-8 or UTF-16, the charset (encoding declaration) is #REQUIRED -- Chris xml-dev: A list for W3C XML Developers.
