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.

Bold characters are also affected. 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/.

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. > Using 7.4. This little problem aside, you might want to upgrade (if not to the development version, at least to 7.5). Aankhen
