 A suggestion could be to allow any text inside the markers, except for
 the marker itself which would need to be escaped. Escaping could take
 the form of doubling the marker:

 ~foo bar~ -- foo bar
 ~foo ~~ bar~ -- foo ~ bar

 As I've not thought this through, I'm pretty sure someone will find a
 huge flaw in this suggestion.

Well, the huge flaw will never be obvious with such solutions...
because the flaw is precisely this: it hides huge flaws.

(Do not bother parsing the above, I'm not sure myself.)

FWIW here is my gut reaction: I'm not a fan (euphemism) of escaping
here, I feel like it adds little value while bumping complexity too
much.

But exploring it might be worth it, if someone wants to try!

Well, preventing users from shooting them in the foot is part of why
`org-emphasis-regexp-components' is not a custom variable (it used to
be, but that led to lots of confusion.)

I hope we can get rid of this variable one day or another.

In the meantime, copying and tweaking is the way to go...

HTH,

I don't see how to do it cleanly without some form of escaping (to allow
anything to be quoted), which goes against the verbatim idea.

A suggestion could be to allow any text inside the markers, except for
the marker itself which would need to be escaped. Escaping could take
the form of doubling the marker:

~foo bar~ -- foo bar
~foo ~~ bar~ -- foo ~ bar

 However, the part about the BORDER regexp is correct I believe: in ~'a ref~,
 the ~ are the MARKERS; ' and f are the BORDER and a re is the BODY.

Thank you, this is it. I had not understood that BORDERs were inside the
MARKERs (although the help text is quite clear in that regard).

Is there a nice way to customize `org-emphasis-regexp-components'? It
does not seem to be exposed to `customize-variable', and copying and

 Thank you for the suggestion. I'm trying to make sense of it:

 org-emphasis-regexp-components is a variable defined in `org.el'.
 Its value is (   ('\{ -   .,:!?;'\)}\\ 
 ,\' . 1)

 Documentation:
 Components used to build the regular expression for emphasis.
 This is a list with five entries.  Terminology:  In an emphasis string
 like  *strong word* , we call the initial space PREMATCH, the final
 space POSTMATCH, the stars MARKERS, s and d are BORDER characters
 and trong wor is the body.  The different components in this variable
 specify what is allowed/forbidden in each part:

 pre  Chars allowed as prematch.  Beginning of line will be allowed 
 too.
 post Chars allowed as postmatch.  End of line will be allowed too.
 border   The chars *forbidden* as border characters.
 body-regexp  A regexp like . to match a body character.  Don't use
  non-shy groups here, and don't allow newline here.
 newline  The maximum number of newlines allowed in an emphasis exp.

 You need to reload Org or to restart Emacs after customizing this.

 I see that body-regexp is . so the problem is not from there. I also
 see that ' is forbidden as a border character, which should be fine in
 my case as I'm using ~. So is the problem that ' is both in prematch
 and postmatch? But in my case I use it as a body character.

 So I'm afraid I don't understand why the ' in ~'a ref~ is not accepted
 as a body character, and what I should do to make sure it is.


See if

  
http://article.gmane.org/gmane.emacs.orgmode/73036/match=org+emphasis+regexp+components

can help make some sense out of the line noise (although it was
triggered by a different question). I believe the problem here is
the BORDER regexp (the one that goes

   
,\'

above), not the BODY one: it forbids newlines, commas, double
and single quotes. Try deleting the single quote from it.

Sorry - I need coffee. I read what you wrote and promptly forgot
