The Haskell 98 Library Report says:

Function toUpper converts a letter to the corresponding upper-case
letter, leaving any other character unchanged.

However, there are two lower case letters that doesn't have the
corresponding upper case letter in hugs (since it's only iso-8859-1
yet).

In hugs:

toUpper 'ÿ' = 'ß'
toUpper 'ß' = '¿'

but they should be unchanged (they have no corresponding upper-case
letter).

Regards,

	Martin
