allow italic quote marks? org-emphasis-regexp-components

[Myles English]

Hello,

Can anyone tell me what to set org-emphasis-regexp-components to in
order to allow italic quote marks?

i.e. /"like this"/

I don't understand the documentation and am just not in the mood to
spend the next hour or so working it out.  (That is a rule of thumb for
me; if it involves a regular expression, it will take at least an hour,
and three cups of tea.)

Thanks,
Myles

I am not helpful here, but would simply like to add that I would also
love an answer to this, as well as times when italics don't seem to work
around periods and commas, like "and /then,/ well, ..." (which does not
italicize for me on emacs 24.5.1, org 8.2.1).

The solution is simpler than you think; you simply need to add ZERO WIDTH
SPACE unicode char between / and " (beginning) and " and / (end).

The default way to do it is

C-x 8 RET zero width space RET

or

C-x 8 RET 200b RET

But I need to use this priceless unicode char to escape stuff like this in
org-mode and so I have bound "0" in "C-x 8" map to insert this char.
Here is how I do it in my init:

Thus I simply need to do C-x 8 0 to insert the ZERO WIDTH SPACE.

To elaborate more, <0> below is where you insert the 200b unicode
characters:

I would like to see /<0>"these surrounding quotes in italics"<0>/.

And Steven,

You need to insert that same char between , and / in /then,/

Won't it break the LaTeX export?

Thanks for your detailed answer Kaushal.  I hadn't heard of a 'zero
length space' before.

I seems to work and manages to produce a pdf but does give this error:

! Package inputenc Error: Unicode char \u8:​ not set up for use with LaTeX.

A quick google search comes up this these:

http://tex.stackexchange.com/questions/83440/inputenc-error-unicode-char-u8-not-set-up-for-use-with-latex
http://tex.stackexchange.com/questions/4268/inputenc-error-unicode-char-u8-error-while-trying-to-write-a-degree-symbol

Based on those solutions, may be you can add

\DeclareUnicodeCharacter{200b}{}

I haven't tried it, so cannot guarantee if that will work.

I regularly generate pdfs and almost all of my org documents would be using
0x200b somewhere. If a pdf generates fine without any visible artifacts and
with all content as expected, I do not look into the tex compilation logs.

This time I checked the log and I don't get that error, but a warning
instead. Note that I also use XeTeX which has unicode support. Below is a
snippet from my log:

Thanks, I'll check it in my Spare Time™.

I hate when TeX gives me *any* errors.  (So does AUCTeX.)

I use something like this:

  (defcustom rasmus/org-latex-unicode-to-tex  '((" " "~")
                                              (" " "\\,")
                                              ("​" ""))
    "list of re rep pairs which are replaced during latex export")
  
  (defun rasmus/org-latex-unicode-to-tex (text backend info)
    "Replace unicode strings with their TeX equivalents.

Currently:  ' ' (no break space) to '~'
            ' ' (thin space) to '\,'
            '​'  (zero width space) to ''."
    (when (org-export-derived-backend-p backend 'latex)
      (cl-loop for (re rep) in rasmus/org-latex-unicode-to-tex do
               (setq text (replace-regexp-in-string re rep text t t)))
      text))
  
  (add-to-list 'org-export-filter-final-output-functions
               'rasmus/org-latex-unicode-to-tex)
