In case someone else need it, here is complete example:
function encode(str) {
  var map = {"š": "\x9a", "Š": "\x8a", "đ": "\xf0", "Đ": "\xd0", "ž": 
"\x9e", "Ž": "\x8e", "č": "\xe8", "Č": "\xc8", "ć": "\xe6", "Ć": 
"\xc6"};
  var dest = "";
  Array.prototype.forEach.call(str, function (ch) {
  	dest += ch in map ? map[ch] : ch;
 	});
  return btoa(dest);
}

Thank you again, you made my day ;o)
