This is Unicode Normalizer in a Common JS module. I’m not affiliated with Matsuza, the original author of Unicode Normalizer.

Installation

npm install unorm

Polyfill

You can use this module as a polyfill for String.prototype.normalize, for example:

console.log('æøåäüö'.normalize('NFKD'));

The module uses some EcmaScript 5 features. Other browsers should use a compability shim, e.g. es5-shim.

Functions

This module exports four functions: nfc, nfd, nfkc, and nfkd; one for each Unicode normalization. In the browser the functions are exported in the unorm global. In CommonJS environments you just require the module. Functions:

• unorm.nfd(str) – Canonical Decomposition
• unorm.nfc(str) – Canonical Decomposition, followed by Canonical Composition
• unorm.nfkd(str) – Compatibility Decomposition
• unorm.nfkc(str) – Compatibility Decomposition, followed by Canonical Composition

Node.JS example

For a longer example, see examples directory.

var unorm = require('unorm');

var text =
  'The \u212B symbol invented by A. J. \u00C5ngstr\u00F6m ' +
  '(1814, L\u00F6gd\u00F6, \u2013 1874) denotes the length ' +
  '10\u207B\u00B9\u2070 m.';

var combining = /[\u0300-\u036F]/g; // Use XRegExp('\\p{M}', 'g'); see example.js.

console.log('Regular:  ' + text);
console.log('NFC:      ' + unorm.nfc(text));
console.log('NFD:      ' + unorm.nfd(text));
console.log('NFKC:     ' + unorm.nfkc(text));
console.log('NFKD: *   ' + unorm.nfkd(text).replace(combining, ''));
console.log(' * = Combining characters removed from decomposed form.');

Road map

As of November 2013. Longer term:

• Look at possible optimizations (speed primarely, module size secondarily)
• Adding functions to quick check normalizations: is_nfc, is_nfd, etc.

Contributers

• Oleg Grenrus is helping to maintain this library. He cleaned up the code base, fixed JSHint errors, created a test suite and updated the normalization data to Unicode 6.3.

Development notes

• Unicode normalization forms report
• Unicode data can be found from http://www.unicode.org/Public/UCD/latest/ucd

To generate new unicode data, run:

cd src/data/src
javac UnormNormalizerBuilder.java
java UnormNormalizerBuilder

produced unormdata.js contains needed table

Execute node benchmark/benchmark.js to run simple benchmarks, if you do any changes which may affect performance.
