PHP，正则表达式问题与非拉丁字符

In a string I'm trying to remove everything inside parentheses with preg_replace but I have some issue with non Latin characters. I tried:

$text = '(Hàng Refurbished) sdfsdfsdfsd (Đen)';
$text = preg_replace('#\([A-Z0-9p{L}]+\)#i', '', $text);
$text = preg_replace('# $#','', $text);
echo $text;

but it's not working

Any suggestion please?

\(.*?\)

Use this to remove all .

See demo.

Use the u modifier, add space in the character class and the unicode property is \p{L}:

$text = preg_replace('#\([A-Z0-9\p{L} ]+\)#ui', '', $text);
//                            __^  __^   __^
