  <p>
  The default implementation replaces:
  <ul>
  <li>Backslash with forward slash.
  <li>Duplicate occurrences of slash with a single slash.
  <li>Any combination of leading slash and control characters (00-1F and 7F) with a
  single "/" or "". For example {@code "  / // foo/bar"} becomes {@code "/foo/bar"}.
  </ul>
