Ah yes, I hadn't noticed that Char.isSpace only recognises Latin-1 space
characters.  I wonder why that is?

I think you'll find that the current implementation of isDigit does only
recognise '0'..'9' (well, it depends on the OS, but the Linux locale
tables only recognise '0'..'9' as digits).  There's a good example in
testsuite/tests/ghc-regress/lib/Char/unicode001.hs.
