Forums Scripts & Popups $encode/$decode

I'm trying to make my own $encode/$decode identifiers. for bordoms sake..

I'm using the method outlined @ http://dictionary.reference.com/search?q=uuencode
It all works ok, exept for occasionaly it drops the last letter when you "reencode" it, because it doesnt have any ` (s) on the end.
ANyone have an idea of how to work out how many ` (s) go on the end of the encoded text?

ie $encode(poo) would be #<&]O````

Not too sure on this but the output seems to be multiples of 4 + 1
mIRCs $decode(,u) works quite happily without them at all

• //var %a = $encode(moo,u) | echo -a %a - $decode(#;6]O,u)

//var -s %a $encode(test) | echo 4 -a %a $decode($remove(%a,`))

//var %a $encode(fair) | echo 4 -a %a $decode($remove(%a,`))

sometimes the ` are needed sometimes they arn't
