How to disable latex writer using "\texorpdfstring" on section captions

[kice]

For example:

``` markdown
## $E=mc^2$
```

convert latex using `pandoc --from markdown --to latex`, I will get

```latex
\hypertarget{emc2}{%
\subsection{\texorpdfstring{\(E=mc^2\)}{E=mc\^{}2}}\label{emc2}}
```

which will render E=mc^2 by exporting pdf; I want to render the math
instead the code on my title.

[John MacFarlane]

Math mode is not allowed in pdf bookmarks, so this is
probably the best we can do.

[Pinglai Ou]

Since I don't need bookmark for PDF, how can I disable this feature?

There's no way to disable it.
You could use a custom template. Change the first
line of the default template from

\PassOptionsToPackage{unicode=true}{hyperref} % options for packages loaded elsewhere

to

\PassOptionsToPackage{unicode=true,bookmarks=false}{hyperref} % options for packages loaded elsewhere

This should disable bookmarks. Let us know if it
works. If it does, we may want to add a `bookmarks`
variable to the default template, so this can be
controlled more easily.

Thx for your reply, but it doesn't work.
I used pandoc -D latex to get the template, changed it and then used

I just tried it, and it worked fine.

pandoc -D latex > temp.latex

Edit first line of temp.latex to include
bookmarks=false in options.

pandoc --template temp.latex MANUAL.txt -o m.pdf

Outcome: m.pdf does not have bookmarks. Perhaps you
made a mistake somewhere in this process?

No, I conver to latex before render the pdf. If you directly render to pdf,
it will be fine. But sometime you need to change the latex formatting
issues.

Usage:

`pandoc -D latex > temp.latex`

edit first line of temp.latex

`pandoc --template=temp.latex -t latex -o test.tex test.md`

markdown for testing
```test.md
# $E=mc^2$
```

latex from pandoc
```test.tex
\begin{document}

\hypertarget{emc2}{%
\section{\texorpdfstring{\(E=mc^2\)}{E=mc\^{}2}}\label{emc2}}

\end{document}
```

Oh sure, your latex file will still contain the
\texorpdfstring command. But it won't generate a
bookmark in the PDF. Is it doing anything else that
you object to? Isn't it harmless?

I want to use mathematical expressions as title, like

```
# $E=mc^2$
```

but pandoc will use \texorpdfstring to make it as a plain string while I
render the latex source file converted from markdown to pdf, instead of
mathematical expressions.

You may try to directly render the markdown in the email to pdf and compare
it to "convert to latex then render it to pdf".

% echo '# $E=mc^2$' | pandoc -o my.tex -s
% pdflatex my.tex
% open my.pdf

Looks just fine, mathematical notation, superscript,
etc. So I'm not sure what you're talking about.

The alternative text in \texorpdfstring only affects
PDF bookmarks, not the printing text in the PDF.

[Pinglai Ou]

please remove the ' in echo command.

echo # $E=mc^2$ | pandoc -o my.tex -s

echo '# $E=mc^2$' will output
```
'# $E=mc^2$'
```
I dont think we need '' to quote the line in markdown.

==================================

Just in case, please save as file to try it.

save below as test.md (not including ``` mark):
```
# $E=mc^2$
```

use `pandoc -t latex -o test.tex test.md` to convert the markdown file to
latex

I think you will get:
```
\hypertarget{emc2}{%
\section{\texorpdfstring{\(E=mc^2\)}{E=mc\^{}2}}\label{emc2}}
```

Then use pandoc to render pdf: `pandoc --pdf-engine=pdflatex -o test.pdf
test.tex`

Use `pandoc --pdf-engine=pdflatex -o direct.pdf test.md` to render markdown
to pdf directly.

Compare two pdf `test.pdf` and `direct.pdf`, you will found that `test.pdf`
didnot render the math correctly.

One more things is that I cannot use pdflatex.exe to render the `test.tex`
file to pdf, you might also want to test it out.

Sorry for not making it clear.

You need the single quotes to avoid interpretation of

When you use pdflatex on this tex file, don't you get
a properly typeset header? I do.

```
\documentclass{article}
\usepackage{hyperref}

\hypertarget{emc2}{%
\section{\texorpdfstring{\(E=mc^2\)}{E=mc\^{}2}}\label{emc2}}

[Pinglai Ou]

No, it doesn't. What I got is in that email. All I got was only two lines
of latex.

Even I added the header, `pandoc --pdf-engine=pdflatex` still cannot render
the math correctly.

When you use pdflatex on this tex file, don't you get
a properly typeset header? I do.
```
\documentclass{article}
\usepackage{hyperref}
\begin{document}
\hypertarget{emc2}{%
\section{\texorpdfstring{\(E=mc^2\)}{E=mc\^{}2}}\label{emc2}}
\end{document}
```

```test.tex
\begin{document}
\hypertarget{emc2}{%
\section{\texorpdfstring{\(E=mc^2\)}{E=mc\^{}2}}\label{emc2}}
\end{document}
```

I'm at a loss here, we may be miscommunicating.

I'd suggest that if you want further help, put
together a zip file with the exact input file
you're using -- and custom template, if any --
and _exact_ instructions for reproducing,
and attach or link to it.

No, it doesn't. What I got is in that email. All I got was only two lines
of latex.

It works well on my Windows machine and pandoc v2.2.3.2 with this command:

echo '# $E=mc^2$' | pandoc --pdf-engine=pdflatex -o my.pdf -s

and even with an intermediate my.tex.
