The %XX characters are URL encoded. They are regular characters in most
cases, but they are characters that have a special meaning in the
context of a URL. The encoding preserves them.

The htmlentities() function (that has been mentioned) is the same thing
but for the context of HTML. It does nothing to determine whether data
is valid (this is called filtering).

Hope that helps.
