Notice the Equal sign is represented with the HTML hexadecimal numeric entity . According to fileformat.info, this character is invalid: http://www.fileformat.info/info/unicode/char/f7d9/index.htm Should this be the character that represents Equal in MathML output? It doesn't appear to have a good representation in the fonts I've tried. You can try too by changing the cell font of the output of the ExportString command at the end of this email.
