IntlChar::charMirror

(PHP 7)

IntlChar::charMirrorGet the "mirror-image" character for a code point

Description

public static IntlChar::charMirror ( mixed $codepoint ) : mixed

Maps the specified character to a "mirror-image" character.

For characters with the Bidi_Mirrored property, implementations sometimes need a "poor man's" mapping to another Unicode character (code point) such that the default glyph may serve as the mirror-image of the default glyph of the specified character. This is useful for text conversion to and from codepages with visual order, and for displays without glyph selection capabilities.
