Check a binary Unicode property for a code point

说明

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.

参数

The integer codepoint value(e.g.0x2603forU+2603 SNOWMAN), or the character encoded as a UTF-8 string(e.g."u{2603}")

The Unicode property to lookup(see theIntlChar::PROPERTY_*constants).

返回值

Returns TRUE or FALSE according to the binary Unicode property value for$codepoint. Also FALSE if$propertyis out of bounds or if the Unicode version does not have data for the property at all, or not for this code point.

范例

Testing different properties

以上例程会输出：

bool(true)
bool(true)
bool(false)
bool(false)
bool(false)
bool(true)
