It is top (for me) of the results of this Google search :

I am afraid that TeX.Stackexchange returns only three results of the
search string "reversed-out text pdflatex", none of which have anything
whatsoever to do with the information sought.  I find this is not
unusual with TeX.Stackexchange, which is one reason why I never use it;
the other reason is the user-rating system; what is the "best" answer
for the majority of users (almost all of whom will be LaTeX users, by
definition) is very rarely the best answer for someone who abhors and
abjures LaTeX.

I did try "TeXdoc latex-symbol"; rather like Stack Exchange, it proved
completely useless.  Had it returned something useful, I would probably
have cited it in preference to the Microsoft result.

Incidentally :

I do not believe that "bad advice" exists; all advice is good -- it is
up to the enquirer to decided whether or not it is appropriate to
his/her needs.

Thank you for your kind words.  I was quite pleased with it, too :-)

I suspect it would be easier and simpler to make an environmental
enquiry and then load CMR<whatever> at the most appropriate size.
