Hi!

say I wanna use "—" as new infix operator: it's the big dash used a bit like parenthesis, especially at the end of sentences —like this.

in ghci directly: Prelude> let (—) a b = a + b

No problem, is accepted and usable. Same in files.

Now I try using (»), a French (amongst others) punctuation sign, typically replaces the quote-ends, « like this ». Doesn't work: <interactive>:2:6: lexical error at character '\187'

I thought Haskell was Unicode-friendly? Why some symbols but not others? :'( _______________________________________________ Beginners mailing list Beginners@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/beginners
