Passing an Email address via the URI

[eluser]TheFuzzy0ne[/eluser]
I'm sure this question has been asked before, but I'll be darned if I can find the answer. I don't want to change the allowed URI characters on account of this. I can also, just convert the @ symbol to some kind of code and decode it with the receiving method, but I'd like to know how everyone else manages.

Thanks.

How about base64 encoding?

Top job! Thanks, Pete!

[eluser]TheFuzzy0ne[/eluser]
Nuts! It's not working. base64_encode seems to add a "=" sign when I encode my Email address.

[eluser]TheFuzzy0ne[/eluser]
Sorted. Just needed to use urlencode(). Thanks again, Pete!

Ow!

The "%" character is not allowed in URIs. Can anyone suggest a good way to encode/decode URIs in CI?

EDIT: I've created two functions to encode/decode base64 encoded strings so that they can be used in the URI. http://ellislab.com/forums/viewthread/107741/
