Polyfill for Utf8toUtf16 for JavaScript

As we know the TextEncoder will drop support utf-16 and other legacy encoding types from Mozilla. Google also confirmed it and Chrome will only remain support utf-16 encoding.

Here is a polyfill implementation for convert utf-8 string to utf-16le

  1. function utf8ToUtf16(s) {
  2. var a = new Uint8Array(s.length * 2),
  3. view = new DataView(a.buffer);
  4. s.split('').forEach(function (c, i) {
  5. //the third parameter equal to true indicate little ending
  6. view.setUint16(i * 2, c.charCodeAt(0), true);
  7. });
  8. return a;
  9. }
