The *standard* French abbreviation for Madame is NOT "M'me" or "M.me" but
"Mme" without confusion, the superscript on final letters "me" is optional.
False positives on "3e" are extremely rare, and writing it as “3ᵉ” does not
change the isolated ambiguities that could exist with a custom numbering
(but for numbersing sections headers, the title is separated by a
punctuation os there's some context such as its presence in a numbered
list, or the presence of explicit word such as articles ("le 3e") and the
grammatical syntax of sentences.
But if semantic is your issue, we could insert an invisible Unicode mark of
abbreviation (notably the invisible abbreviation dot, which may be rendered
as a dot in some contexts where distinctions by styles cannot be used, or
could be rendered by using superscripts for letters glued after it). We
have such characters for mathematics (invisible addition mark and invisible
multiplication marks (to disambiguate cases in formulas, such as a number
followed by a fraction: does "3 1/2" mean 3.5 or 1.5 ?)
