Removing this line should fix this:

https://github.com/vuejs/vitepress/blob/bae47f708264722a92f8feeb7a8f3fbecc756196/src/node/markdown/markdown.ts#L93

But I am unsure why it was added in first place. It was ported from VuePress.

Edit: Just tested. It does everything same as the default formatter except for parsing emojis. Let it remain there, and simply encode the resultant string.

Done!
