Encoding API

Elide supports the standard JavaScript types TextEncoder and TextDecoder. These classes can be used to obtain byte-arrays of strings in different encodings, or to obtain strings from byte arrays with different encodings.

Supported Encodings

Elide supports several encodings via the TextEncoder and TextDecoder constructors:

Support	Charset	Encoding (Label)	Notes
🟢 Supported.	`ISO_8859_1`	`iso-8859-1`
🟢 Supported.	`ASCII`	`ascii`
🟢 Supported.	`UTF_8`	`utf-8`	Default encoding
🔴 Not supported yet.	`UTF_16`	`utf-16`
🔴 Not supported yet.	`UTF_32`	`utf-32`
🔴 Not supported yet.	(Other charsets)

Classes

TextEncoder Encode strings into byte array representations: 🟢 Supported.
TextDecoder Decode byte arrays into string representations: 🟢 Supported.

`TextEncoder`

// create an encoder; by default, it uses utf-8
const encoder = new TextEncoder();
encoder.encoding         // returns 'utf-8'
encoder.encode("hello")  // returns `Uint8Array([...])`

The TextEncoder class behaves very similarly to how it behaves in a browser, or under Node.js; the only difference is that Elide supports additional encodings, on top of the default, which is utf-8.

`TextEncoder` Properties

TextEncoder.encoding: 🟢 Supported.

`TextEncoder` Methods

TextEncoder.encode: 🟢 Supported.
TextEncoder.encodeInto: 🟢 Supported.

`TextDecoder`

// create a decoder; by default, it uses utf-8
const decoder = new TextDecoder();
decoder.encoding         // returns 'utf-8'
const input = new Uint8Array([104, 101, 108, 108, 111]);
decoder.decode(input)  // returns 'hello'

The TextDecoder class behaves identically to how it behaves in a browser, or under Node.js.

`TextDecoder` Properties

TextDecoder.encoding: 🟢 Supported.

`TextDecoder` Methods

TextDecoder.decode: 🟢 Supported.
