Hey Folks,

I’m posting AppleScript on the Keyboard Maestro forum using a code-block.

A user reported a compile problem with my code.

Rendered by Discourse:

```plaintext
set foundList to cng("<td class=\"pricesens\">.+title=[[:punct:]](price sensitive)[[:punct:]]>", "\\1", foundList) of me

```

What should be:

Double-Quote-Backslash-Backslash-1-Double-Quote

Is rendering as:

Double-Quote-Backslash-BackTick-Double-Quote.

`“\\1”`

Using a `<code></code>` block on the forum I can get the few characters above to show up correctly by adding a backslash, but it the code-block doesn’t like my complete line of code.

Using `<pre></pre>` tags doesn’t help on the forum, although it works perfectly well in a normal html page.

Code-blocks should be completely unadulterated, so I conclude this is a bug.

–  
Regards,  
Christopher Stone

Seems like a bug, yes:

Indented 4 spaces

```
set foundList to cng("<td class=\"pricesens\">.+title=[[:punct:]](price sensitive)[[:punct:]]>", "\\1", foundList) of me

```

As a code block

`set foundList to cng("<td class=\"pricesens\">.+title=[[:punct:]](price sensitive)[[:punct:]]>", "\\1", foundList) of me`

The two backslashes in front of the 1 are not rendering correctly. You could try it on Babelmark as well…

Hey Folks,

This bug is still not fixed.

Code rendering needs to be bombproof reliable…

They aren’t on commonmark yet, and this is tagged to be reviewed when they move to it.

And … it now works!

```plaintext
\\1

```

`\\1`

```
\\1

```

Yay

````
```
\\1
```

`\\1`

    \\1

````

It will take a bit till this is rolled out but new engine fixes it:

> [@CommonMark testing started here!](https://meta.discourse.org/t/commonmark-testing-started-here/65121):
>
> Per our [migration plans](https://meta.discourse.org/t/discourse-commonmark-migration-plans-confetti-ball-balloon), I just enabled [markdown.it](https://github.com/markdown-it/markdown-it) at Meta. It is an excellent [CommonMark](http://commonmark.org/) compliant engine. I expect quite a few edges to be found during this period of testing. Do not open bugs about the new Engine, just reply here. I/we will be updating the top post here with the list of issues and striking out stuff as it is fixed. Current known issues (to be fixed)white_check_mark Onebox vanishes after you start typing and works not-super consistently white_check_mark pending…
