+# get-east-asian-width
+
+> Determine the [East Asian Width](https://unicode.org/reports/tr11/) of a Unicode character
+
+> East Asian Width categorizes Unicode characters based on their occupied space in East Asian typography, which helps in text layout and alignment, particularly in languages like Japanese, Chinese, and Korean.
+
+Unlike other similar packages, this package uses the latest Unicode data (which changes each year).
+
+## Install
+
+```sh
+npm install get-east-asian-width
+```
+
+## Usage
+
+```js
+import {eastAsianWidth, eastAsianWidthType} from 'get-east-asian-width';
+
+const codePoint = '字'.codePointAt(0);
+
+console.log(eastAsianWidth(codePoint));
+//=> 2
+
+console.log(eastAsianWidthType(codePoint));
+//=> 'wide'
+```
+
+## `eastAsianWidth(codePoint: number, options?: object): 1 | 2`
+
+Returns the width as a number for the given code point.
+
+### options
+
+Type: `object`
+
+#### ambiguousAsWide
+
+Type: `boolean`\
+Default: `false`
+
+Whether to treat an `'ambiguous'` character as wide.
+
+```js
+import {eastAsianWidth} from 'get-east-asian-width';
+
+const codePoint = '⛣'.codePointAt(0);
+
+console.log(eastAsianWidth(codePoint));
+//=> 1
+
+console.log(eastAsianWidth(codePoint, {ambiguousAsWide: true}));
+//=> 2
+```
+
+> Ambiguous characters behave like wide or narrow characters depending on the context (language tag, script identification, associated font, source of data, or explicit markup; all can provide the context). **If the context cannot be established reliably, they should be treated as narrow characters by default.**
+> - http://www.unicode.org/reports/tr11/
+
+## `eastAsianWidthType(codePoint: number): 'fullwidth' | 'halfwidth' | 'wide' | 'narrow' | 'neutral' | 'ambiguous'`
+
+Returns the type of “East Asian Width” for the given code point.
