[patch] ox.latex.el: Add missing character warnings

["Juan Manuel Macías" <maciaschain@posteo.net>]

[-- Attachment #1: Type: text/plain, Size: 611 bytes --]


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
