windows-1252

windows-1252 is a robust JavaScript implementation of the windows-1252 character encoding as defined by the Encoding Standard.

This encoding is known under the following names: ansi_x3.4-1968, ascii, cp1252, cp819, csisolatin1, ibm819, iso-8859-1, iso-ir-100, iso8859-1, iso88591, iso_8859-1, iso_8859-1:1987, l1, latin1, us-ascii, windows-1252, and x-cp1252.

Installation

Via npm:

npm install windows-1252

Via Bower:

bower install windows-1252

Via Component:

component install mathiasbynens/windows-1252

In a browser:

<script src="windows-1252.js"></script>

In Narwhal, Node.js, and RingoJS:

var windows1252 = require('windows-1252');

In Rhino:

load('windows1252.js');

Using an AMD loader like RequireJS:

require(
  {
    'paths': {
      'windows1252': 'path/to/windows1252'
    }
  },
  ['windows1252'],
  function(windows1252) {
    console.log(windows1252);
  }
);

API

windows1252.version

A string representing the semantic version number.

windows1252.labels

An array of strings, each representing a label for this encoding.

windows1252.encode(input, options)

This function takes a plain text string (the input parameter) and encodes it according to windows-1252. The return value is a ‘byte string’, i.e. a string of which each item represents an octet as per windows-1252.

var encodedData = windows1252.encode(text);

The optional options object and its mode property can be used to set the error mode. For encoding, the error mode can be 'fatal' (the default) or 'html'.

var encodedData = windows1252.encode(text, {
  'mode': 'html'
});
// If `text` contains a symbol that cannot be represented in windows-1252,
// instead of throwing an error, it will return an HTML entity for the symbol.

windows1252.decode(input, options)

This function takes a byte string (the input parameter) and decodes it according to windows-1252.

var text = windows1252.decode(encodedData);

The optional options object and its mode property can be used to set the error mode. For decoding, the error mode can be 'replacement' (the default) or 'fatal'.

var text = windows1252.decode(encodedData, {
  'mode': 'fatal'
});
// If `encodedData` contains an invalid byte for the windows-1252 encoding,
// instead of replacing it with U+FFFD in the output, an error is thrown.

Support

windows-1252 is designed to work in at least Node.js v0.10.0, Narwhal 0.3.2, RingoJS 0.8-0.9, PhantomJS 1.9.0, Rhino 1.7RC4, as well as old and modern versions of Chrome, Firefox, Safari, Opera, and Internet Explorer.

Unit tests & code coverage

After cloning this repository, run npm install to install the dependencies needed for development and testing. You may want to install Istanbul globally using npm install istanbul -g.

Once that’s done, you can run the unit tests in Node using npm test or node tests/tests.js. To run the tests in Rhino, Ringo, Narwhal, and web browsers as well, use grunt test.

To generate the code coverage report, use grunt cover.
