How to forbidden wordpress url exchange `&` to `#038;`?

Question

I want to pass some value through url in wordpress, but I met some trouble that wordpress will exchange & to #038; automatically, how to make a & still as a & ?

I noticed in wp-includes/formatting.php, there has many rules to exchange symbols, I tried modify some code, but failed.

some link like

site.com?this=that&that=this will output to the web browser address like site.com?this=that#038that=this

and the page can not get the value in the part that=this

how to setting correctly? thanks.

You can disable wptexturize() by adding this in a functions.php file inside your template folder (or add it to the existing one):

remove_filter('the_content', 'wptexturize');

But note that this will of course disable all the "cleaning", not just the '&' conversion.

If you prefer to just get rid of the ampersand conversion you can comment line 962 in formatting.php. I post lines 961 and 962 bellow (this is from an unaltered WP 3.1):

// Converts lone & characters into & (a.k.a. &)  
$content = preg_replace('/&([^#])(?![a-z1-4]{1,8};)/i', '&$1', $content);
