- Can the Char type hold the full range of Unicode characters? This has been true in GHC for some time, and is now true in Hugs. I don't think it's true in nhc98 (please correct me if I'm wrong).

You're wrong :-). nhc98 has always had 32-bit characters internally.

I checked the nhc98 sources, and it seems that maxBound::Char is '\255'.

Yes, but nothing prevents you from creating a larger character by e.g. (toEnum 0x12345678) :: Char

Then I respectfully submit a bug report :-) It shouldn't be possible to create a value of Char outside minBound..maxBound. It's possible the report doesn't say this explicitly, but see for example section 6.3.4. Cheers, Simon
