fromEnum (c :: Char)

[Serge D. Mechveliani]

People,
I need to convert  Char <-> Int  in a possibly _standard_ way for 
Haskell -- and also in an efficient way. In particular, it must not 
spend 100 comparisons in a look through the listing of Char.

I use               ord :: Char -> Int  and  chr :: Int -> Char.
Is this all right?
Thank you in advance for advice,
