TextEncoder

The TextEncoder interface takes a stream of code points as input and emits a stream of UTF-8 bytes.

Example

const encoder = new TextEncoder()
const view = encoder.encode('€')
console.log(view); // Uint8Array(3) [226, 130, 172]

Constructor

TextEncoder()

Returns a newly constructed TextEncoder that will generate a byte stream with UTF-8 encoding.

Properties

The TextEncoder interface doesn't inherit any property.

TextEncoder.prototype.encodingRead only

Always returns "utf-8".

Methods

The TextEncoder interface doesn't inherit any method.

TextEncoder.prototype.encode()

Takes a USVString as input, and returns a Uint8Array containing UTF-8 encoded text.

TextEncoder.prototype.encodeInto()

Takes a USVString to encode and a destination Uint8Array to put resulting UTF-8 encoded text into, and returns a dictionary object indicating the progress of the encoding. This is potentially more performant than the older encode() method.
