emailjs-stringencoding

This is a polyfill for the Encoding Living Standard API for the Web, allowing encoding and decoding of textual data to and from Typed Array buffers for binary data in JavaScript

Basic examples and unit tests are included.

API Overview

Scripts

  <script src="emailjs-stringencoding.js"></script>

Basic Usage

  var uint8array = TextEncoder(encoding).encode(string);
  var string = TextDecoder(encoding).decode(uint8array);

Streaming Decode

  var string = "", decoder = TextDecoder(encoding), buffer;
  while (buffer = next_chunk()) {
    string += decoder.decode(buffer, {stream:true});
  }
  string += decoder.decode(); // finish the stream

Test

Start a web server in the project root

$ python -m SimpleHTTPServer 8000

Then run the tests here.

Encodings

All encodings from the Encoding specification are supported:

utf-8 ibm864 ibm866 iso-8859-2 iso-8859-3 iso-8859-4 iso-8859-5 iso-8859-6 iso-8859-7 iso-8859-8 iso-8859-10 iso-8859-13 iso-8859-14 iso-8859-15 iso-8859-16 koi8-r koi8-u macintosh windows-874 windows-1250 windows-1251 windows-1252 windows-1253 windows-1254 windows-1255 windows-1256 windows-1257 windows-1258 x-mac-cyrillic gbk gb18030 hz-gb-2312 big5 euc-jp iso-2022-jp shift_jis euc-kr iso-2022-kr utf-16 utf-16be

(Some encodings may be supported under other names, e.g. ascii, iso-8859-1, etc. See Encoding for additional labels for each encoding.)

Encodings other than utf-8, utf-16 and utf-16be require an additional encoding-indexes.js file to be included. It is rather large (539kB uncompressed, 182kB gzipped); portions may be deleted if support for some encodings is not required.
