## Install

This package is [pure ESM](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c). If you're not ready yet, install an older version of this program, 3.1.0 (`npm i email-all-chars-within-ascii@3.1.0`).

```bash
npm i email-all-chars-within-ascii
```

## Quick Take

```js
import { strict as assert } from "assert";

import { within } from "email-all-chars-within-ascii";

// enforces all characters to be within ASCII:
assert.deepEqual(within("<div>Motörhead</div>"), [
  {
    type: "character",
    line: 1,
    column: 9,
    positionIdx: 8,
    value: "ö",
    codePoint: 246,
    UTF32Hex: "00f6",
  },
]);

// enforces line lengths (500 is best for email):
assert.deepEqual(within("abcde", { lineLength: 3 }), [
  {
    type: "line length",
    line: 1,
    column: 5,
    positionIdx: 5,
    value: 5,
  },
]);
```
