Rationale for the attached patch: It seems that a common problem that
users have with exporting to LaTeX is unicode characters that cannot be
represented in pdfLaTeX or LuaLaTeX/XelaTeX. In the Unicode TeX engines
the warning is insidious, since the missing character warning is not
preceded by a 'warning' string.
Naturally, the added Org warnings do not solve the problem, but at least
they give some clues on how to properly adjust the document.
Best regards,
Juan Manuel
