How Do I Make A Tag Page For A Tag With an Apostrophe?

[Thysbelon]

I'm automatically generating tag pages for all of my tags. One of my tags contains an apostrophe. The URL generated is
/Tags/example%27s-tag/ for the tag "example's tag". This URL is fine, however, the name of the folder for the tag generated in the _site folder is also example%27s-tag; this folder's index.html is impossible to navigate to unless I type
/Tags/example%2527s-tag/ in the browser's address bar.
I tested this with a simple test server: if I manually change the name of the folder to example's-tag, it seems to work correctly.
I would like to know how to configure Eleventy to set the name of the folder to example's-tag.
Thank you for reading.

I think nunjucks is the reason I was struggling. I made two similar templates:

test's.njk

---
customKey: "test's"
permalink: "/{{ customKey | replace(''',`'`) }}/"
---
<h1>Test</h1>

test's2.11ty.js

module.exports = {

data() {
	return {
		customKey: "test's2",
		permalink: data => `/${data.customKey}/`
	}
},

render(data) {
return `
	<h1>test2</h1>
`;
}
}

The njk template generated test's. The 11ty.js template generated test's2

I think you'd want to use the slugify filter on the customKey permalink.

---
customKey: "test's"
permalink: "/{{ customKey | slugify }}/"
---
<h1>{{ customKey }}</h1>

npm run build
