## What is this?
This is a list of certain named character references, that due to legacy
reasons, don’t need a trailing semicolon in HTML.
For example, `©` is perfectly fine for `©`!
## When should I use this?
Maybe when you’re writing an HTML parser or minifier, but otherwise probably
never!
Even then, it might be better to use [`parse-entities`][parse-entities] or
[`stringify-entities`][stringify-entities].
## Install
This package is [ESM only][esm].
In Node.js (version 14.14+, 16.0+), install with [npm][]:
```sh
npm install character-entities-legacy
```
In Deno with [`esm.sh`][esmsh]:
```js
import {characterEntitiesLegacy} from 'https://esm.sh/character-entities-legacy@2'
```
In browsers with [`esm.sh`][esmsh]:
```html
import {characterEntitiesLegacy} from 'https://esm.sh/character-entities-legacy@2?bundle'
```
## Use
```js
import {characterEntitiesLegacy} from 'character-entities-legacy'
console.log(characterEntitiesLegacy.includes('copy')) // => true
console.log(characterEntitiesLegacy.includes('frac34')) // => true
console.log(characterEntitiesLegacy.includes('sup1')) // => true
```
## API
This package exports the identifier `characterEntitiesLegacy`.
There is no default export.
### `characterEntitiesLegacy`
List of (case sensitive) legacy character entity names (`Array`).
[`wooorm/character-entities`][character-entities] holds their decoded values.
See [`whatwg/html`][html] for more info.
## Types
This package is fully typed with [TypeScript][].
It exports no additional types.
## Compatibility
This package is at least compatible with all maintained versions of Node.js.
As of now, that is Node.js 14.14+ and 16.0+.
It also works in Deno and modern browsers.
## Security
This package is safe.
