perl form parsing! HELP!

Hey guys,

I'm really stuck on this one and i'm sure there must be an easier way, but i'm not completly sure what it is.

Basically, i have a client that wants to be able to edit the html on their webpage, via the web and without using ftp, so i've written a REALLY basic bit of perl that will open a text file print it inside a text box, then save it back out when its submitted.

The problem is, is that all the non alpha numeric characters are converted to %whatever (ie ! is %21).

In the past i've just used a simple regex to replace the code with the proper character and be done with it, but i did a solution that will do them all, without me having to do it all by hand (cos there must be 1000's of characters, and processing that many would be a nightmare wouldnt it?)

$content =~ s/%21/\!/g;'

Any ideas?

you can see the script running at http://www.magicshop.co.uk/admin/index.pl hit the submit button and you'll see what i mean!

any help would be appreciated.

Thanks!
