TextEncoder()

The TextEncoder() constructor returns a newly created utf-8 TextEncoder object.

Syntax

encoder = new TextEncoder();

Parameters

TextEncoder() takes no parameters since Firefox 48 and Chrome 53

Note: Prior to Firefox 48 and Chrome 53, an encoding type label was accepted as a paramer to the TextEncoder object, since then both browsers have removed support for any encoder type other than utf-8, to match the spec. Any type label passed into the TextEncoder constructor will now be ignored and a utf-8 TextEncoder will be created.

Exceptions

TextEncoder() throws no exceptions since Firefox 48 and Chrome 53

Note: Prior to Firefox 48 and Chrome 53 an exception would be thrown for an unknown encoding type.
