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.
