I need to allow the 'okina character through the following code
<?php $char = preg_replace('/[\x00-\x08\x0B\x0C\x0E-\x1F\x80-\xFF]/u', '', $char); ?>
I've tried to find a clear explanation of how the ranges work here and how to pick out one letter from a range with no luck. How do I do that?
Thanks
