IntlChar::isMirrored — Check if code point has the Bidi_Mirrored property

### 说明

public static IntlChar::isMirrored(int|string `$codepoint`): ?bool

This property is set for characters that are commonly used in Right-To-Left contexts and need to be displayed with a "mirrored" glyph.

### 参数

`codepoint`

  The int codepoint value (e.g. `0x2603` for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. `"\u{2603}"`)

### 返回值

Returns `true` if `codepoint` has the Bidi_Mirrored property, `false` if not. Returns `null` on failure.

### 示例

`<?php
var_dump(IntlChar::isMirrored("A"));
var_dump(IntlChar::isMirrored("<"));
var_dump(IntlChar::isMirrored("("));
?>`

以上示例会输出：

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