This is the convention you will find enforced if you publish a book or article in a professional journal.
I'm sorry, but I don't care if this comes from the mouth of God, this makes no sense. Why should the rule change if you are using a fixed- versus variable-width font? The rule does not depend on the physical characteristics of the letters, it depends on the interpretation of the sentence. What if you are writing by hand? Does the rule change if you are using block letters versus cursive?
Further, I'm not sure that any author's guidelines that I have ever read for submitting articles in the economics journals even specifies which you should do, other than to say something like "for other issues [i.e. this sort of thing] follow the rules given in XXX." [Note, period inside the quotation marks because that is how the quoted sentence is written.] XXX would just be APA style, Chicago, or something else like that. In fact, I just checked the American Economic Review (generally the top journal in econ) and it says nothing at all about it. And it specifies alot of crap. But maybe this is just because it's economics and not a field more concerned with language. We use mathematics to avoid any confusing language. Other possibly confusing language doesn't matter.
