The characters allowed before and after emphasis can be configured via
`#+pandoc-emphasis-pre` and `#+pandoc-emphasis-post`, respectively. This
allows to change which strings are recognized as emphasized text on a
per-document or even per-paragraph basis. The allowed characters must be
given as (Haskell) string.
#+pandoc-emphasis-pre: "-\t ('\"{"
#+pandoc-emphasis-post: "-\t\n .,:!?;'\")}["
If the argument cannot be read as a string, the default value is
restored.
