Hmm... there might be two different problems here. Try adding
"<silent>" to eliminate the error message, like below:

 iunmap <silent> <Up>
 vunmap <silent> <Up>

But if you're getting weird characters, it may be that your console
doesn't recognize these characters in the first place, many old ones
don't. What system are you on?

It may be that your system doesn't recoginize these keys, and so Vim
doesn't map them. (I use <silent> to map them so you wouldn't know.)
That would explain why when you try to unmap them, they don't exist.

This is the very reason Vim has traditionally had modes and
alphanumeric keystrokes for every command--ancient systems (and maybe
yours!) didn't have keyboards with arrow keys, separate number pad,
function keys, etc. Vim is great, it can run on the oldest, slowest
system in existance. But Cream can't. ;)

You might try a test at the command line like

  imap <Up> :echo "test"

Does it produce an error or message?
