Haskell: convert unicode integer to actual unicode character

Question

Suppose that my Haskell function is given an input, which is supposed to be the number of a unicode code point. How can one convert this to the corresponding character?

Example:

123 to '{'.

I think { is decimal 123, not hex 0x0123. – Reid Barton Mar 28 '10 at 13:30 — Reid Barton, Mar 28 '10 at 13:30

Use toEnum. (Chars implement the Enum typeclass.)

Yep, or `chr` from `Data.Char`. – Reid Barton Mar 28 '10 at 13:23
