How and why do you url encode and decode?

Well less of me and more of a guy called Brian Wilson. I had a file that I wanted to url encode - since the filename I had used was littered with spaces and at the time couldn't precisely remember what to change!

Anyway to cut a long story short if you want to know the whys and hows or url encoding go visit Brian's page - http://www.blooberry.com/indexdot/html/topics/urlencoding.htm

The cool thing is he has placed some code on the site so you can actually encode your unencoded url! Very useful, giving you the details of the JavaScript functions String.charCodeAt and String.fromCharCode.
