Conversion between UTF-8 ArrayBuffer and String
Using TextEncoder and TextDecoder
var uint8array = new TextEncoder("utf-8").encode("Plain Text");var string = new TextDecoder().decode(uint8array);console.log(uint8array ,string )
function stringToUint(string) { var string = btoa(unescape(encodeURIComponent(string))), charList = string.split(''), uintArray = []; for (var i = 0; i < charList.length; i++) { uintArray.push(charList[i].charCodeAt(0)); } return new Uint8Array(uintArray);}function uintToString(uintArray) { var encodedString = String.fromCharCode.apply(null, uintArray), decodedString = decodeURIComponent(escape(atob(encodedString))); return decodedString;}I have done, with some help from the internet, these little functions, they should solve your problems! Here is the working JSFiddle.
EDIT:
Since the source of the Uint8Array is external and you can't use atob you just need to remove it(working fiddle):
function uintToString(uintArray) { var encodedString = String.fromCharCode.apply(null, uintArray), decodedString = decodeURIComponent(escape(encodedString)); return decodedString;}Warning: escape and unescape is removed from web standards. See this.
This should work:
