IntlChar::getBidiPairedBracket — Get the paired bracket character for a code point
$codepoint): int|string|nullMaps the specified character to its paired bracket character.
For Bidi_Paired_Bracket_Type!=None, this is the same as IntlChar::charMirror().
Otherwise codepoint itself is returned.
codepointThe int codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")
Returns the paired bracket code point, or codepoint itself if there is no such mapping. Returns
null on failure.
The return type will be int unless the code point was passed as a UTF-8 string, in which case a string will be returned.

var_dump(IntlChar::getBidiPairedBracket(91));
var_dump(IntlChar::getBidiPairedBracket('['));
