Hello,

I use Org-mode to take notes. I found that when there are nesting braces inside \emph{ }, \textit{ }, etc. the output is unexpected. The following org text

\emph{{n+1}-a}
\textit{a{b}c}

will be translated as LaTeX expressions

\emph\{\{n+1\}-a\}
\textit\{a\{b\}c\}

Can this be fixed?
Best,
Yue

I'm not sure it is a bug. Could you specify what do you expect in these
cases?


Note that there are native org-syntax for \emph and \textbf

*n+1 - a* 
/a{b}c/

(info "(org) Emphasis and Monospace")

Hello Yue,

Posting your mail below back to the list where you have a better chance
of getting the right explanation. I totally understand that many times
copy directly latex chunk is a nice feature org-mode offers.

From your example below, exporting the following script to latex would
work ok in org-mode.

#+BEGIN_SRC org
#+options: toc:nil
#+LATEX_HEADER: \usepackage{amsthm}
#+LATEX_HEADER:\theoremstyle{theorem}
#+LATEX_HEADER: \newtheorem{theorem}{Theorem}\usepackage{setspace}
#+end_src

* Theorem

 The longest word in this sentence is \emph{emphasized}.
 \begin{theorem}
   An emphasized a word looks \emph{distinguished}.
 \end{theorem}

Yes, for my part I usually wrap into a source block, if I need native
latex syntax

#+BEGIN_SRC latex
\emph{{n+1}-a}
\textit{a{b}c}
#+end_src

I don't know if it is the case by design or if it is a bug.

HTH,
Jeremie

Org only supports a limited part of the LaTeX syntax as raw syntax. This
is not AucTeX mode!

For complex macros (e.g., with nested braces), you need to use dedicated
environments, as pointed out by Jérémie.
