Create URL from cb field

I am trying to generate a url from contents of several cb fields, but I need to 'urlencode' the contents of each field or of the final url string. How can I do this with, say, a field delimiter, or with another field type? Is there a urlencode() equivalent to use?
Thanks.

You'd have to string it together with a delimiter field,but you won't be able to urlencode it.

Is there a urlencode() equivalent to use?

Nope.
