It seems the issue has been fixed

for some reason the encoding of some ascii characters is broken you can insert this code for a temperary fix:

[log, console.log] = [console.log, function(...args) {
  var map = args[0];
  if(!Array.isArray(map) && [9617,9619].indexOf(map.charCodeAt(map.length-1)) !== -1)
    return log(map.split('').map(a => a.charCodeAt(0) === 9617 ? '.' : a.charCodeAt(0) === 9619 ? 'X' : a).join(''));
  log(...args);
}];

Please resolve this issue as it's with the site no the kata itself.
