IntlChar::hasBinaryProperty — Check a binary Unicode property for a code point
Description
Checks a binary Unicode property for a code point.
Unicode, especially in version 3.2, defines many more properties than the original set in UnicodeData.txt.
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 » http://www.unicode.org/ucd/. For names of Unicode properties see the UCD file PropertyAliases.txt.
