I've noticed a discrepancy in by version of Hugs with experimental Unicode support enabled, based on the 20040109 codebase. It's exemplified by this:

[[ Main> '\x10ffff' '\1114111' Main> maxBound::Char '\255' Main> ]]

It appears that this value is hardcoded in Hugs/Prelude.hs, rather than obtained from the runtime environment in some way.

I think you're using an old version of Hugs/Prelude.hs. You need to copy the new versions of files in libraries/Hugs from the source bundle to wherever Hugs is looking for them (-q will tell you where).
