wp_sanitize_redirect removing valid URIs characters

[omarabid]

I'm using the wp_redirect function on one of my plugins. One of my users found out that in the redirect, the brackets are removed from the URL.

I dug a little bit and found the culprit to be the function "wp_sanitize_redirect" which removes the brackets.

Here is the regex expression that detects and removes unwanted characters

$location = preg_replace('|[^a-z0-9-~+_.?#=&;,/:%!]|i', '', $location);

Here are the accepted characters in a URI*

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-._~:/?#[]@!$&'()*+,;=

So is there are a reason to remove this characters or is this a bug?
