Hello, when I compare two files, it seems, that the encoding is ignored. My files differ in the encoding declaration. One files starts with <?xml version="1.0" encoding="UTF-8"?>, while the other uses ASCII. This difference is not highlighted. More important, if I merge a section from the UTF-8 file to the ASCII file, french characters are not converted to its numerical entity, if they don't fit into 7bit.
