The "special" characters like & \ % are not really special to TeX, they
are only special by virtue of the default catcode settings, and
suitable for hand authored TeX. For machine generated TeX you may as
well just make all of these ordinary characters.
See the stylesheet for making the pdf versions of the MathML spec
(in the XML zip archive of the spec) This uses pdflatex, but with a
setup that makes all these characters normal (and uses #, pound
character as the catcode0 escape character , so #section{...} etc.
As I happened to know that there were no pounds in the MathML spec
this saves on having to check for and quote special characters. |
