I'd be glad my level for debugging Emacs Lisp was that high. Unfortunately,
not sure it is...

How do you do in such a case?  Adding edebug calls in some functions?  Other
way?

Done it:

--8<---------------cut here---------------start------------->8---
    ;; Add the unbreakable space as allowed character after an emphasis
    ;; string, and modify the maximum number of newlines allowed in an
    ;; emphasis
    (setq org-emphasis-regexp-components
          '(" 	('\"{"
            "- 	., :!?;'\")}\\"
            " 	\r\n,\"'"
            "."
            4))
--8<---------------cut here---------------end--------------->8---

None of the above 2 mentionned problem seems to disappear, though, on this
ECM:

--8<---------------cut here---------------start------------->8---
  - /S'il faut remodéliser ce qui est dans le code COBOL, comment faire ?
    Discussions avec le business, relire le COBOL ? Chez nous, la
    vite vis-à-vis du marché./

    The above "question" (in a FAQ) should be in italics. But, to do so, we
    have to split it in multiple chunks in italics:

  - /S'il faut remodéliser ce qui est dans le code COBOL, comment faire ?/
    /Discussions avec le business, relire le COBOL ?/ /Chez nous, la
    tarification n'est pas modélisée./ /Pourtant, c'est là qu'il faut aller
    vite vis-à-vis du marché./

  - Le /challenge/ : efficacité et rapidité...

    Here, the word challenge is not in italics because the following character
    is an unbreakable space (*not* a normal space).

        Note -- I'm forced to use such characters in order to get my LaTeX PDF
        correctly outputted. Anyway, under Emacs, the normal space is
        converted to an unbreakable one, each time it is before a ":"
        character, so that's easy to do, but the output is not correctly
        converted.
--8<---------------cut here---------------end--------------->8---

Yes. I mean: would I write pure LaTeX from scratch, I would insert `~' here
and there when I want an unbreakable space to be produced (resulting in a nice
PDF output).

Here, as I write pure Org that gets converted, I need to insert a real
unbreakable space in my Org source. That's the source of some problems, such
as the second above mentionned (emphasis not correct after word "challenge").

    Note -- Currently, that character is not converted to a tilde when
    exporting to LaTeX. That could be a good option, though.

Best regards,
  Seb
