Im having the next error while working with SetaPDF, PHP 8 under Laravel Framework.

“Array and string offset access syntax with curly braces is no longer supported”

the error is on the SetaPDF/Core

    if ($_lastRc4Key !== $key) {

            $k = str_repeat($key, 256 / strlen($key) + 1);

            $rc4 = range(0, 255);

            $j = 0;

            for ($i = 0; $i < 256; $i++) {

                $rc4[$i] = $rc4[$j = ($j + ($t = $rc4[$i]) + ord($k{$i})) % 256];

                $rc4[$j] = $t;

            }

            $_lastRc4Key = $key;

            $_lastRc4KeyValue = $rc4;

 

Is someway to make PHP8 work with string offset access, any update on SetaPDF version? Thanks
