I'm exporting the following org file (left-side) to a LaTeX pdf file.
The org file contains the multiple dashes in the ~code~ =verbatim=
format. The exported PDF file doesn't have the correct number of dashes.

|----------------+-----------------------------------|
| Original org   |   Exported  tex file  section     |

|                |    ....                           |

| 1. ~-~         |    \label{sec:org532ffa5}         |
| 2. ~--~        |    \begin{enumerate}              |
| 3. ~---~       |    \item \texttt{-}               |
| 4. ~----~      |    \item \texttt{-{}-}            |
| 5. ~-----~     |    \item \texttt{-{}--}           |
| 6. ~a------b~  |    \item \texttt{-{}--{}-}        |
|                |    \item \texttt{-{}--{}--}       |
|* verbatim      |    \item \texttt{a-{}--{}--{}-b}  |
| 1. =-=         |    \end{enumerate}                |
| 2. =--=        |                                   |
| 3. =---=       |    \section{verbatim}             |
| 4. =----=      |    \label{sec:org4a05ec4}         |
| 5. =-----=     |    \begin{enumerate}              |
| 6. =a------b=  |    \item \texttt{-}               |
|                |    \item \texttt{-{}-}            |
|                |    \item \texttt{-{}--}           |
|                |    \item \texttt{-{}--{}-}        |
|                |    \item \texttt{-{}--{}--}       |
|                |    \item \texttt{a-{}--{}--{}-b}  |
|                |    \end{enumerate}                |
|                |    ...                            |
|----------------+-----------------------------------|

These multiple dashes need `{}` separator in between (i.e. `-{}-`).
However, I believe that ~----~ should become \texttt{-{}-{}-{}-{}-}
(actual 4 dashes) instead of \texttt{-{}--{}-} (dash + en.dash + dash)?

It may be needed {} in between every dash. (I read from here
<https://tex.stackexchange.com/a/9814/292504>)

Basically what I'm saying is that. I might need the following in
order to have the correct number of dashes.

|----------------+--------------------------------------|
| Original org   |   Maybe it should have exported      |
|----------------+--------------------------------------|
|                |   ...                                |
|* code          |   \section{code}                     |
| 1. ~-~         |   \label{sec:org532ffa5}             |
| 2. ~--~        |   \begin{enumerate}                  |
| 3. ~---~       |   \item \texttt{-}                   |
| 4. ~----~      |   \item \texttt{-{}-}                |
| 5. ~-----~     |   \item \texttt{-{}-{}-}             |
| 6. ~a------b~  |   \item \texttt{-{}-{}-{}-}          |
|                |   \item \texttt{-{}-{}-{}-{}-}       |
|* verbatim      |   \item \texttt{a-{}-{}-{}-{}-{}-b}  |
| 1. =-=         |   \end{enumerate}                    |
| 2. =--=        |                                      |
| 3. =---=       |   \section{verbatim}                 |
| 4. =----=      |   \label{sec:org4a05ec4}             |
| 5. =-----=     |   \begin{enumerate}                  |
| 6. =a------b=  |   \item \texttt{-}                   |
|                |   \item \texttt{-{}-}                |
|                |   \item \texttt{-{}-{}-}             |
|                |   \item \texttt{-{}-{}-{}-}          |
|                |   \item \texttt{-{}-{}-{}-{}-}       |
|                |   \item \texttt{a-{}-{}-{}-{}-{}-b}  |
|                |   \end{enumerate}                    |
|                |    ...                               |
|----------------+--------------------------------------|

The possible place this bug might reside:
It's possible that while exporting, it replaces -- with -{}-.
So 4 dashes (----) has 2 -- so each couple gets replaced
with -{}- finally forming -{}--{}-.


I was suggested to report this possible bug in the following forum question
<https://emacs.stackexchange.com/questions/76777/org-export-latex-multiple-dashes-in-code-verbatim-turn-into-wrong-number-of?noredirect=1#comment127290_76777>
.


If this was an intentional feature I'm sorry.

I think I even found a solution much easier solution.

Just replace each - dash with {-} when exporting latex.

In other words:

|---------------+-------------------------------------|
| Original org  | New suggestion                      |
|---------------+-------------------------------------|
|               | ...                                 |
| * code        | \section{code}                      |
| 1. ~-~        | \label{sec:org532ffa5}              |
| 2. ~--~       | \begin{enumerate}                   |
| 3. ~---~      | \item \texttt{{-}}                  |
| 4. ~----~     | \item \texttt{{-}{-}}               |
| 5. ~-----~    | \item \texttt{{-}{-}{-}}            |
| 6. ~a------b~ | \item \texttt{{-}{-}{-}{-}}         |
|               | \item \texttt{{-}{-}{-}{-}{-}}      |
| * verbatim    | \item \texttt{a{-}{-}{-}{-}{-}{-}b} |
| 1. =-=        | \end{enumerate}                     |
| 2. =--=       |                                     |
| 3. =---=      | \section{verbatim}                  |
| 4. =----=     | \label{sec:org4a05ec4}              |
| 5. =-----=    | \begin{enumerate}                   |
| 6. =a------b= | \item \texttt{{-}}                  |
|               | \item \texttt{{-}{-}}               |
|               | \item \texttt{{-}{-}{-}}            |
|               | \item \texttt{{-}{-}{-}{-}}         |
|               | \item \texttt{{-}{-}{-}{-}{-}}      |
|               | \item \texttt{a{-}{-}{-}{-}{-}{-}b} |
|               | \end{enumerate}                     |
|               | ...                                 |
|---------------+-------------------------------------|

This will ensure each - character as a separate character.
This seems much easier to implement and readable.
