$ ocaml
         Objective Caml version 3.10.2

# let c = 'ö';;
Characters 8-9:
   let c = 'ö';;
           ^
Syntax error

Meanwhile, in another terminal window:

$ ocaml
         Objective Caml version 3.10.2

# let c  = 'ö';;
val c : char = '\246'
#

I prefer my strings to be composed of chars that represent characters.
