Most Markdown code block syntax highlighters have pretty good support for TeX based languages out of the box. I think it's reasonable to assume blocks otherwise unmarked on this site are going to be tex.
Source:
~~~markdown
```
\textbf{bob}
```
~~~
Output:
```
\textbf{bob}
```
Of course setting the language should also work:
Source:
~~~markdown
```tex
\textbf{bob}
```
~~~
Output:
```tex
\textbf{bob}
```
Right not it appears the language is just not recognized.

We've added TeX to our highlightjs highlighting library as it [isn't in the list](https://highlightjs.org/download/) for a default download.
We've also made `tex` the default language for this community but please bear in mind that if you want unformatted code blocks you now need to declare that explicitly, so:
~~~none
```
\textbf{bob}
```
~~~
produces:
```
\textbf{bob}
```
and:
~~~none
```none
\textbf{bob}
```
~~~
produces:
```none
\textbf{bob}
```
