||
## 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].
|
||
|
||

|
||
This package is [ESM only][esm].
|
||

|
||
|
||
```sh
|
||
npm install character-entities-legacy
|
||
```
|
||
|
||
In Deno with [Skypack][]:
|
||
|
||
```js
|
||
import {characterEntitiesLegacy} from 'https://cdn.skypack.dev/character-entities-legacy@2?dts'

console.log(characterEntitiesLegacy.includes('copy')) // => true

console.log(characterEntitiesLegacy.includes('frac34')) // => true
