Hello!

I'm not an experienced mailing list user, but I will try to be brief.
Please excuse my lack of common courtesy.


* Problem

  There needs to be a way to coax Org into interpreting something as an
  emphasis marker, even if it ordinarily would not look like it (for
  example, because it is in the middle of a regular word, when putting
  emphasis on only part of a word.)

  - Version of Org: 9.1.6
  - Version of Emacs: GNU Emacs 25.3.2 (x86_64-pc-linux-gnu)


* Suggested Solution

  Include the Unicode zero width no-break space character (U+feff) in
  both ~pre~ and ~post~ sections of ~org-emphasis-regexp-components~.

  I currently have trouble accessing code.orgmode.org (502 Bad Gateway),
  but I imagine the solution to look something like

      --- org.el      2018-06-06 09:33:56.602335268 +0200
      +++ org-zwnbsp-emphasis.el      2018-06-06 09:39:37.985958647 +0200

       This is a list with five entries.  Terminology:  In an emphasis string
       like \" *strong word* \", we call the initial space PREMATCH, the final

  This has the added tiny benefit that legacy documents that still use
  U+feff as a byte order mark may be able to get emphasis also on their
  first word... (Not sure if this is a problem, actually, just throwing
  it out there.)


* Discussion

  - Does this even make sense to begin with, or is it just me?

  - Is the zero-width no-break space the most sensible character to do
    this with?

    I see the zero-width joiner as the alternative – but that appears to
    have more legitimate uses inside words, especially in some
    non-Western scripts such as Arabic and Indic. I use U+feff mostly
    because it is actually sort of a space but not quite.


* Related Reports

  I found an email in the archives which touches on the same point[1],
  but suggests a more radical change.
