Quoting URIs

ambs has asked for the wisdom of the Perl Monks concerning the following question:

I need to pass as parameter for a script a complete URL. This URL can itself be an URL for a script. So, I need to quote special characters like '&' and '?'.

Is there any module to quote special characters on URIs? Like the standard s/ /%20/ one?

Thanks in advance.
