This problem/error has nothing at all to do with URLs.
When you want an ampersand in text/html, you write  &amp;
in general, not just in URLs.

In text/plain, you write  AT&T
In text/html , you write  AT&amp;T

For example, inspect the source text of
 http://en.wikipedia.org/wiki/ATandT
and look for  AT&amp;T .
