Do you have auto-formatting on save configured in Emacs -- perhaps even
via a starter kit like Doom Emacs, so that you're only half aware of it?
And are you by any chance on macOS, which ships with the tidy program
(HTML Tidy) by default? Or failing that, did you install it manually?

To cut a long-story short: HTML auto-formatting on save runs tidy, which
mangles the HTML in various ways, including this CDATA thing. This also
happens in buffers with generated Org export output.

I posted the long version to the mailing list in February:
https://list.orgmode.org/CAEPTPEwOZjJLX1jyFmVR6jarsocyuD=Zf7HJ1i9G4SfWk4mUpQ@mail.gmail.com/

I suggested a patch, but it probably got buried in the noise:
https://list.orgmode.org/20220228140750.75761-1-dafydd.lukes@gmail.com/

Instead, I see that another fix was merged yesterday (for different
reasons AFAICS, but it should help with this auto-formatting issue too):
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=d7a55bbd537314d2776b082bd92a1a08b3edc84e

This should be enough for HTML exports, but two more tweaks are needed
for ODT exports in ox-odt.el -- see my original patch. Or use
https://github.com/kjambunathan/org-mode-ox-odt, which has already
incorporated them.

+1 on that, although obviously, I'm aware it's quite a chore.

Best,

Hello,

I am customizing my org-mode installation but there is something that I
don't understand.

When I execute the following statement:

```
(setq org-html-mathjax-template

"
<script type=\"text/x-mathjax-config\">
    MathJax.Hub.Config({
        displayAlign: \"%ALIGN\",
        displayIndent: \"%INDENT\",
        \"HTML-CSS\": { scale: %SCALE,
                        linebreaks: { automatic: \"%LINEBREAKS\" },
                        webFont: \"%FONT\"
                       },
        SVG: {scale: %SCALE,
              linebreaks: { automatic: \"%LINEBREAKS\" },
              font: \"%FONT\"},
        NativeMML: {scale: %SCALE},
        TeX: { equationNumbers: {autoNumber: \"%AUTONUMBER\"},
               MultLineWidth: \"%MULTLINEWIDTH\",
               TagSide: \"%TAGSIDE\",
               TagIndent: \"%TAGINDENT\"
        }
    });
</script>
<script src=\"%PATH\"></script>
")
```

A `CDATA` tag gets appended in my HTML export as shown below:

```html
  <script type="text/x-mathjax-config">
<![CDATA[
    mathjax.hub.config({
        displayalign: "center",
        displayindent: "0em",
        "html-css": { scale: 100,
                        linebreaks: { automatic: "false" },
                        webfont: "TeX"
                       },
        svg: {scale: 100,
              linebreaks: { automatic: "false" },
              font: "TeX"},
        nativemml: {scale: 100},
        tex: { equationnumbers: {autonumber: "AMS"},
               multlinewidth: "85%",
               tagside: "right",
               tagindent: ".8em"
        }
    });
  ]]>
  </script>
  <script src=
  "
https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-AMS_HTML
"
  type="text/javascript">
</script>
```

As you can see above, when I set the variable I have no CDATA tag on it.
Where does this tag come from? The problem is that the CDATA tag messes up
with the MathJax configuration parser, as it expects a JavaScript script
inside. But, instead, it finds a CDATA tag that, while it might be valid
according to W3, the MathJax parser throws an `eval` error in the console
since it tries to parse the body of that HTML node.

Where does this CDATA tag gets added automatically and how can I modify
this behavior?

Diego Rodriguez.
