Script Preparation code:
var bytes = [84,104,105,115,32,105,115,32,97,32,115,97,109,112,108,101,32,112,97,114,97,103,114,97,112,104,46]; var bufferArray = new Uint16Array(bytes); var decoder = new TextDecoder(); // default 'utf-8' or 'utf8'
Tests:
String.fromCharCode
String.fromCharCode.apply(null, bufferArray);
TextDecoder
decoder.decode(bufferArray);
