説明
public static IntlChar::getIntPropertyValue

, int $property
) : int
Gets the property value for an enumerated or integer Unicode property for a code point. Also returns binary and mask property values.
パラメータ
codepoint
- コードポイントを表す int 型の値 (例: U+2603 SNOWMAN を表す
0x2603
)、あるいは UTF-8 文字列としてエンコードされた文字 (例:"\u{2603}"
)。 property
- 調べたい Unicode プロパティ (定数

Returns 0

is out of bounds or if the Unicode version does not
