SOLUTIONS:

LINE 212
Change this value:
$output .= ‘ 0x’.str_pad(dechex(ord($string{$i})), 2, ‘0’, STR_PAD_LEFT);
With this value:
$output .= ‘ 0x’.str_pad(dechex(ord($string[$i])), 2, ‘0’, STR_PAD_LEFT);

LINE 989
Change this value:
$strtr_preg_quote[$escapeables{$i}] = $delimiter.$escapeables{$i};
With this value:
$strtr_preg_quote[$escapeables[$i]] = $delimiter.$escapeables{$i};

I have tested this solution several times and it appears to be correct.

Hoping to have been useful, however, I await confirmation from you.

Good day and good work.
