        This document tests the operation of
        <code>SVGGlobal.binaryToString()</code>.  The tests use the two
        required encodings, UTF-8 and UTF-16.  It consists of five subtests,
        the result of which is represented with a rectangle (red for fail,
        green for pass).  The test is passed if all five rectangles are green:

      <ol>
        <li>
          Decoding a valid UTF-8 sequence, which includes characters from all
          planes.
        </li>
        <li>
          Decoding a valid UTF-16 sequence with a BE BOM, same characters as
          subtest 1.
        </li>
        <li>
          Decoding a valid UTF-16 sequence with an LE BOM, same characters as
          subtest 1.
        </li>
        <li>
          Attempting to decode various invalid UTF-8 sequences (partial multiple
          byte sequences, characters outside the assigned Unicode range,
          overlong sequences, etc.).
        </li>
        <li>
          Attempting to decode an invalid UTF-16 sequences (bad surrogates).
