  Str = Replace(Str, "&", "&")
  Str = Replace(Str, ">", ">")
  Str = Replace(Str, "&lt;", "<")
  Str = Replace(Str, "&nbsp;", CHR(32))
     Str = Replace(Str, "&nbsp;", CHR(9))
  Str = Replace(Str, "&#160;&#160;&#160;&#160;", CHR(9))
  Str = Replace(Str, "&quot;", CHR(34))
  Str = Replace(Str, "&#39;", CHR(39))
  Str = Replace(Str, "", CHR(13))
  Str = Replace(Str, "<br>", CHR(10))
