Normalize

Normalize a string with utf-8 characters.

Usage

Download: normalize.js or normalize.min.js

$npm install normalize-strings --save

or

$bower install normalize-strings --save

Just use the string you want to normalize as argument

console.log(normalize('Åland')) // Aland

You can import it as a commonJS module

var n = require('normalize');

console.log(n('Åland')) // Aland

or as an AMD module

define(['normalize'],
function(n) {
  console.log(n('Åland')) // Aland
});

How it works?

Normalize is based on Django's urlify scrapping character's map from [http://unicode.org/charts/charindex.html]

Why?

JS compares strings according to the utf-8 code of each character. This means, for example, that õ comes after z (i.e. 'õ' > 'z' === true) and this causes disasters when sorting strings. With normalize, you can correctly fix this. Althought you have available String.prototype.localCompare which solve it, it is not yet supported on some browsers (i.e. IE10 and below).

Using a custom charmap

You can use your own defined charmap for substitutions providing an object as a second parameter to the normalize function.

normalize('AABB', {
  '97': 'E',
  '98': 'Z'
}); // EEZZ
