   Checks a binary Unicode property for a code point.

  <para>
   Unicode, especially in version 3.2, defines many more properties than the original set in UnicodeData.txt.
  </para>
  <para>
   The properties APIs are intended to reflect Unicode properties as defined in the Unicode Character Database (UCD)
   and Unicode Technical Reports (UTR). For details about the properties see
   <link xlink:href="http://www.unicode.org/ucd/">http://www.unicode.org/ucd/</link>.
   For names of Unicode properties see the UCD file PropertyAliases.txt.
