* Feature request: modify italic regexp list to include non-breaking space and other characters

Sample code:
  Using /a/’s and /b/’s, write add /x/ + 2.
           ^         ^                ^ ^
       Right single quotation mark    Non-breaking space

Expected HTML export:
  Using <i>a</i>’s and <i>b</i>’s, write <i>x</i> + 2.

Actual HTML export:
  Using /a/’s and /b/’s, write add /x/ + 2.

If it's not clear, the sample code uses the unicode character "right single character" instead of an apostrophe and "non-breaking space" instead of regular white space. 

It makes sense to use these characters this way, however, orgmode neither displays the italic expressions correctly nor exports them correctly. 

I believe older versions of orgmode worked in the expected way. 

How can I modify the regexp list? Bold characters are also affected.

Using 7.4.

Interestingly, the development version treats this differently, as it
considers all the text from the first slash to the last part of the
emphasis:

,----
| <p>Using <i>a/’s and /b/’s, write add /x</i> + 2.
| </p>
`----

(This behaviour occurs in the original Org buffer as well, in case
anyone’s wondering.  The exported HTML was just the easiest way to
show it.)

These two variables are used to configure the regexp:

,----[ C-h v org-emphasis-alist RET ]
| org-emphasis-alist is a variable defined in `org.el'.
| Its value is (("*" bold "<b>" "</b>")
|  ("/" italic "<i>" "</i>")
|  ("_" underline "<span style=\"text-decoration:underline;\">" "</span>")
|  ("=" org-code "<code>" "</code>" verbatim)
|  ("~" org-verbatim "<code>" "</code>" verbatim)
|  ("+"
|   (:strike-through t)
|   "<del>" "</del>"))
|
|
| Documentation:
| Special syntax for emphasized text.
| Text starting and ending with a special character will be emphasized, for
| example *bold*, _underlined_ and /italic/.  This variable sets the marker
| characters, the face to be used by font-lock for highlighting in Org-mode
| Emacs buffers, and the HTML tags to be used for this.
| For LaTeX export, see the variable `org-export-latex-emphasis-alist'.
| For DocBook export, see the variable `org-export-docbook-emphasis-alist'.
| Use customize to modify this, or restart Emacs after changing it.
|
| You can customize this variable.
`----

,----[ C-h v org-emphasis-regexp-components RET ]
| org-emphasis-regexp-components is a variable defined in `org.el'.
| Its value is (" 	('\"{" "- 	.,:!?;'\")}\\" " 	
\n,\"'" "." 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.
|
| Use customize to modify this, or restart Emacs after changing it.
|
| You can customize this variable.
|
| [back]
`----

I’d say that ‘pre’/‘post’ should really contain [[:space:]], but then
Org’s syntax table seems to treat the non-breaking space as
punctuation, so that wouldn’t help.  You could try adding the
character itself to both of those categories for a fix.  You’ll need
to restart Emacs afterwards (unless you used the Customize interface)
so that ‘org-emph-re’ is updated accordingly.

This little problem aside, you might want to upgrade (if not to the
development version, at least to 7.5).

Ouch. I hope the devs consider that to be a bug and fix it in the development version.
