**Env:**

- hugo 0.65
- In my theme, I use mathjax to render tex equation.

**Expected:**

Keep equation block (blocked by `$$`

or `$`

) as verbatim (Markdown render engine do not escape the content blocked by equation block)

**Actual rendering:**

The current markdown rendering may escape chars in equation block , such as `_`

to `<em>`

:

input:

```
$$
L\left(\mathbf{e}_{j i}\right)=-\mathbf{S}_{j i, j}+\log \sum_{k=1}^{N} \exp \left(\mathbf{S}_{j i, k}\right)
$$
```

output:

```
$$
L\left(\mathbf{e}<em>{j i}\right)=-\mathbf{S}</em>{j i, j}+\log \sum_{k=1}^{N} \exp \left(\mathbf{S}_{j i, k}\right)
$$
```

That is, in the html output, it is expected to be rendered as follow equation:

But the actual html output is:

**I can’t** find how to config hugo or Goldmark render engine. So I put forward this question.

Any help will be appreciated!
