docs-rst: Don't mangle with UTF-8 chars on LaTeX/PDF output

Browse Source 
pdflatex doesn't accept using some UTF-8 chars, like
"equal or less than" or "equal or greater than" chars. However,
the media documents use them. So, we need to use XeLaTeX for
conversion, and a font that accepts such characters.
