|
- Jhc is the only implementation that allows unrestricted use of the Unicode character set in Haskell source, treating input as UTF-8.
|
|
|
|
- Hugs treats input as being in the encoding specified by the current locale, but permits Unicode only in comments and character and string literals.
|
|
|
|
- Others treat source code as Latin-1.
|
|
|
|
- Jhc supports several uses of unicode characters instead of the haskell

keywords.
