Lexemes challenge: support for klingon letters

[fuddl]

Currently klingon letters in the lexermes challange look like this:

With a dedicated font it could look like this:

You could simply define it as a fallback

@font-face {
  font-family: 'DIn pIqaD';
  src: url(dist/DIn pIqaD.woff);
  unicode-range: U+F8D0-F8E9,U+F8F0-F8F9,U+F8FD-F8FF;
}

body, input, select {
    font-family: "Open Sans", 'DIn pIqaD', sans-serif;
    font-size: 14px;
    background: #FFF;
}

or scope it to a specific language:

td:lang(tlh) {
   font-family: 'DIn pIqaD', monospace;
}
