This question already has an answer here:

Athough discussion on that question is still going on (even if third ways exists), it seems that larger spaces after the end of a sentence is preferable in English. By default, LaTeX puts wider spaces after a period (full stop).

I took the habit of escaping spaces (i.e., writing i.e.\, or to make it more clear, i.e.\␣) after

  • Latin locutions, as

    • etc.
    • cf.
  • Mathematical expressions, as

    • s.t. (such that)
    • w.r.t. (with respect to)
    • resp. (respectively)

However, according to this post, which quotes Chapter 14 of the Texbook, and according to any bbl file, spaces after names initial should not be escaped. That is, one write

Donald~E. Knuth

and not

Donald~E.\ Knuth

I'm confused: shouldn't that space be escaped as well?

    There is no way that a wider space should appear after an abbreviated middle initial. I can't imagine it being proper in any sense. – Steven B. Segletes Nov 10 '15 at 16:14

    Am I missing something (this is from the Not So Short Intro.): If a period follows an uppercase letter, this is not taken as a sentence ending, since periods after uppercase letters normally occur in abbreviations. – jak123 Nov 10 '15 at 16:26

    @jak123 This does not cover all the cases. For instance, in French, if your name is Christophe, then you abbreviate it as Ch., and not as C.. But thanks for your remark, which solve partially my problem. – Clément Nov 10 '15 at 16:30

    +1 for citing the cartoon. the comment by @jak123 covers the situation where the abbreviation is just a single (uppercase) initial. where a different abbreviation style ("Ch." for "Christophe") is applied, then a "slash-space" should be used; this is probably a good idea even if \frenchspacing is used for a bibliography (as it often is), to accommodate such things as author-year citations, which take the string in question out of its original context. – barbara beeton Nov 10 '15 at 17:04
