Bug with Char.isAlpha

Hi!

I am using the precompiled windows version of ghc-6.4.2 and for some reason

Prelude> Char.isAlpha '§'

returns true. Hugs however, is of the opinion that the paragraph sign is 
not an alphabetic character and so am I. I did not find any rationale 
for this behavior (as  no system I know of treats the §-sign as an 
alphabetic char) so I think it is a bug and should be fixed.

Regards,
Michael

PS: I have not been using ghc(i) for too long, so if I missed something, 
please let me know.
