API Overview

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

Encodings

Only utf-8 and UTF-8 are supported.

Non-Standard Behavior

Only utf-8 and UTF-8 are supported.

Motivation

Binary size matters, especially on a mobile phone. Safari on iOS does not support TextDecoder or TextEncoder.
