Can unescaped heading text be used?

[2-3-5-7]

I have a heading like this

## 1.1 aaa/bbb
after render it became
<h2 id="1-1-aaa-x2F-bbb"><a href="#1-1-aaa-x2F-bbb" class="headerlink" title="1.1 aaa/bbb"></a>1.1 aaa/bbb</h2>

it should be
<h2 id="1-1-aaa-bbb" ><a href="#1-1-aaa-bbb" class="headerlink" title="1.1 aaa/bbb"></a>1.1 aaa/bbb</h2>

fixed by modifying the renderer.js file

// use unescaped heading text
heading(escaped_text, level, text) {
const { anchorAlias, headerIds, modifyAnchors } = this.options;
const { _headingId } = this;
...
}

It's escaped here:

hexo-renderer-marked/lib/renderer.js

Line 193 in f134063

text = escape(isSmarty ? smartypants(cap[0], quotes) : cap[0]);
