Your experiment illustrate's David Lee's point regarding the difficulty of this whole problem. We can't really tell what's going on without access to your entire toolchain. (It's unlikely that the encoding of the characters in this email is byte-identical with the files you created.) It's possible that your editor changed the character encoding of your text when you changed the XML declaration (emacs does this)! It's also possible (I haven't checked) that the bytes in your text are valid UTF-8 *and* valid ISO-8859-1, althought they would represent different characters in the two systems. -Mike On 12/28/2012 3:37 PM, Costello, Roger L. wrote: > Thanks Chris for pointing us to that article: XML on the Web has Failed > > I am making my way through it. > > This statement in the article piqued my interest: > > ... determining the actual character encoding of an > XML document is a prerequisite for determining its > well-formedness ... > > I decided to do an experiment. > > I created this XML document and encoded each character in the document using the iso-8859-1 encoding and in the encoding="..."
