Here's a summary of the state of Unicode support in GHC and other compilers. There are several aspects:

- 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'.

- Can you use (some encoding of) Unicode for your Haskell source files? I don't think this is true in any Haskell compiler right now.

Many years ago, hbc claimed to be the only compiler with support for this.

What encoding(s) did hbc allow in source files? The docs only mention unicode characters inside character & string literals. Cheers, Simon
