the_permalink() returns wrong string

There is such thing urldecode() ?

The question is not challenge enough? why it is ignored. I am waiting online to see the answers…

I tried workaround solutions, non of them works, the string is unreplaceable, why?

1)
<?php
$source = array(“%3F”, “%3D”);
$target = array(“?”, “=”);
$content = urldecode(str_replace($source, $target, urlencode(the_permalink())));
echo $content;
?>
” rel=”bookmark” title=”Permanent Link to <?php the_title(); ?>”> <?php the_title(); ?> </h2>

2)
href=”<?php str_replace(“%3Fp%3D”, “?p=”, the_permalink()); ?>” rel=”bookmark” title=”<?php the_title(); ?>”

looking for straight answer, where is my hero?
