allow a second paramater for uri_unescape, to list what characters one wants unescaped or not too

Perhaps also allow a second paramater for
uri_unescape, to list what characters one wants unescaped or not too,
just like uri_escape.

Could you give an example?

$_ = $node->getAttribute('href'); s!^/a/notifications.php\?redir=([^&]+)&.+!$1! or die; s/%25/%/g; s/%26/&/g; s/%2B/+/g; s/%2F/\//g; s/%3A/:/g; s/%3D/=/g; s/%3F/?/g; s/%5C/\\/g; s/%7C/|/g; $node->setAttribute( 'href', $_ ); If uri_unescape accepted an additional argument, '%&+/:=?\|', all that wouldn't have been necessary. You might ask why I can't just use plain uri_unescape? Well that would unescape CJK characters, resulting in an invalid URL.
