Checks a binary Unicode property for a code point.

<p class="para">
Unicode, especially in version 3.2, defines many more properties than the original set in UnicodeData.txt.

<p class="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
<a href="http://www.unicode.org/ucd/" class="link external">» http://www.unicode.org/ucd/</a>.
For names of Unicode properties see the UCD file PropertyAliases.txt.
