Does quoting help?

victor@ss07:~/Desktop$ [1] DIRNAME="A Test"
victor@ss07:~/Desktop$ [1] echo $DIRNAME
A Test

victor@ss07:~/Desktop$ [1] touch !$/foo
touch "A Test"/foo

victor@ss07:~/Desktop$ [1] mkdir "A Test"/"A subfolder"
victor@ss07:~/Desktop$ [1] touch !$/foo2
touch "A Test"/"A subfolder"/foo2

victor@ss07:~/Desktop$ [1] cp -Rv "$DIRNAME" aNewFolder
`A Test' -> `aNewFolder'
`A Test/foo' -> `aNewFolder/foo'
`A Test/A subfolder' -> `aNewFolder/A subfolder'
`A Test/A subfolder/foo2' -> `aNewFolder/A subfolder/foo2'

Not sure if that would cope with the \040 that you mention though. I
suspect if you can get the label un-escaped you should be able to get
away with it.
