I have a better solution here:

function base64encode(str) {
  let encode = encodeURIComponent(str).replace(/%([a-f0-9]{2})/gi, (m, $1) => String.fromCharCode(parseInt($1, 16)))
  return btoa(encode)
}
function base64decode(str) {
  let decode = atob(str).replace(/[\x80-\uffff]/g, (m) => `%${m.charCodeAt(0).toString(16).padStart(2, '0')}`)
  return decodeURIComponent(decode)
}

function tests() {
  Array.from([
