unescape-unicode is a Node.js library that can convert a Unicode escape ("\uxxxx" notation) into its corresponding Unicode character.
Install using npm
:
$ npm install --save unescape-unicode
You'll need to have at least Node.js 8 or newer.
Converts the Unicode escape within input
.
The Unicode escape must be valid, although it can just contain hexadecimal segment. That is, it has to match the following pattern:
(\\u)?[0-9A-Fa-f]{4}
An error will be thrown if no valid Unicode escape is found.
Optionally, a start
index can be provided to begin conversion at a specific location within input
. If start
is not
specified, null
, or negative, the conversion will begin at the start of input
.
const unescapeUnicode = require('unescape-unicode');
unescapeUnicode('\\u2665');
//=> "♥"
unescapeUnicode('2665');
//=> "♥"
unescapeUnicode('I \\u2665 Unicode!', 2);
//=> "♥"
unescapeUnicode('\\u03bb');
//=> "λ"
unescapeUnicode('03BB');
//=> "λ"
