// Error

To convert non-ASCII characters to BASE64 encoding, you must insert a transcoding link in between, and then use these two methods.

function B64encode (str) {  return  btoa (encodeURIComponent (str));} function B64decode (str) {  return  decodeuricomponent (Atob (str));} B64encode (//  "Juu0jujejuewjuu1jue1juje"/ / "Hello"
