So, as a relative neophyte here, I was all excited to share my nifty answer to a question about making PDF files reproducible, but when posting it, I found that tex.stackexchange.com converted my Tab character to spaces, which made my answer seem to be inexplicably broken to anyone who cuts and pastes it into a file.

I can sort of see why other stackexchange sites might want to untabify everything, but it doesn't seem to make sense here. Is there a workaround for this? Or maybe some toggle switch that the admins of tex.stackexchange.com can flip?

Thanks!

Tabs are standardised by both plain TeX and LaTeX to spaces, so for almost all cases there is not really a need for 'us' to worry'. However, tab replacement is not controlled 'locally' for the site in any case: this is something that only the Powers can alter. I suspect it may be a feature of the editor system ...

You must use the HTML entity &#9; for the tab character. Since this only works in HTML, not MarkDown code blocks, you'll also need to use &lt; for the < character.

For example, if you select this, you can see it has embedded tabs:

<A>					<B>

The above can be written on stackexchange as

<pre><code>&lt;A>&#9;&#9;&#9;&#9;&#9;&lt;B></code></pre>
