Encoding Web Addresses

Some characters have special meanings

There are a number of characters that have special meanings when they appear in web addresses. Those characters may also be needed as a part of the content of the address. In order that everything processing the address is able to tell the difference between those characters with and without their special meanings you need to encode the ones where you don't want the special meaning to apply. JavaScript provides not just one but two functions that you can call to do this encoding for you.
