IntlChar::hasBinaryProperty

Check a binary Unicode property for a code point

&reftitle.description; public static ``bool``null```IntlChar::hasBinaryProperty` ``int``string```codepoint` `int` `property`

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 &url.unicode.ucd;. For names of Unicode properties see the UCD file PropertyAliases.txt.

&reftitle.parameters;

`codepoint`

- &intl.codepoint.parameter;

`property`

- &intl.property.parameter;
&reftitle.returnvalues;

Returns &true; or &false; according to the binary Unicode property value for `codepoint`. Also &false; if `property` is out of bounds or if the Unicode version does not have data for the property at all, or not for this code point. Returns &null; on failure.
