iso-8859-16 is a robust JavaScript implementation of the iso-8859-16 character encoding as defined by the Encoding Standard.

This encoding is known under the following names: , and iso-8859-16.


Via npm:

npm install iso-8859-16

In a browser:

<script src="iso-8859-16.js"></script>

In Node.js, io.js, Narwhal, and RingoJS:

var iso885916 = require('iso-8859-16');

In Rhino:


Using an AMD loader like RequireJS:

    'paths': {
      'iso-8859-16': 'path/to/iso-8859-16'
  function(iso885916) {



A string representing the semantic version number.


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

iso885916.encode(input, options)

This function takes a plain text string (the input parameter) and encodes it according to iso-8859-16. The return value is a ‘byte string’, i.e. a string of which each item represents an octet as per iso-8859-16.

const encodedData = iso885916.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'.

const encodedData = iso885916.encode(text, {
  'mode': 'html'
// If `text` contains a symbol that cannot be represented in iso-8859-16, 
// instead of throwing an error, it will return an HTML entity for the symbol. 

iso885916.decode(input, options)

This function takes a byte string (the input parameter) and decodes it according to iso-8859-16.

const text = iso885916.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'.

const text = iso885916.decode(encodedData, {
  'mode': 'fatal'
// If `encodedData` contains an invalid byte for the iso-8859-16 encoding, 
// instead of replacing it with U+FFFD in the output, an error is thrown. 

For decoding a buffer (e.g. from fs.readFile) use buffer.toString('binary') to get the byte string which decode takes.


iso-8859-16 is designed to work in at least Node.js v0.10.0, io.js v1.0.0, Narwhal 0.3.2, RingoJS 0.8-0.11, PhantomJS 1.9.0, Rhino 1.7RC4, as well as old and modern versions of Chrome, Firefox, Safari, Opera, Edge, and Internet Explorer.


Similar modules for other single-byte legacy encodings are available.
