      <p>
        This tests that methods on the SVGTextContentElement interface
        that take an index to a character or a number of characters
        actually interpret these as indexes to or numbers of UTF-16 code
        units. To test this, a character from outside the Basic Multilingual Plane 
        (U+10000; LINEAR B SYLLABLE B008) is used in a text string. 
        This character is stored in UTF-16 as a surrogate pair.
      </p>
      <p>
        The test consists of 5 sub-tests, which test the methods
        methods on the SVGTextContentElement interface.  The result
        of each sub-test is shown as a small rectangle: black
        indicates that the sub-test did not run, red indicates that
        the sub-test failed and green indicates that the sub-test
        succeeded.
      </p>
    </d:testDescription>
    <d:operatorScript xmlns="http://www.w3.org/1999/xhtml">
      <p>
        Run the test. No interaction required.
      </p>
      <p>
        The test relies on support for WebFonts - either SVG Fonts, or WOFF, or OpenType.

      <p>
        The test is passed if all 5 rectangles are green.
