Thanks Earnie, but that is not what I am looking for. It is essentially similar to urlencode or rawurlencode. I am looking for a function that does the work like the one present at the bottom of the page here:

http://www.blooberry.com/indexdot/html/topics/urlencoding.htm

For eg:

http://example.com/q=12 &12grt key=value;<>+,.()!*

is converted to

http://example.com/q=12%20&12grt%20key=value;%3C%3E+,.()!*

 Hi,

http://www.google.com/search?q=url+encoding+site%3Aapi.drupal.org leads you to two api functions url [1] and drupal_urlencode [2].  Are these what you need?

[1] http://api.drupal.org/api/function/url
[2] http://api.drupal.org/api/function/drupal_urlencode
