(** Character operations. *)
external code : char -> int = "%identity"
(** Return the ASCII code of the argument. *)
val chr : int -> char
(** Return the character with the given ASCII code.
Raise [Invalid_argument "Char.chr"] if the argument is
outside the range 0--255. *)
val escaped : char -> string
(** Return a string representing the given character,
with special characters escaped following the lexical conventions
of Objective Caml. *)
val lowercase : char -> char
(** Convert the given character to its equivalent lowercase character. *)
val uppercase : char -> char
(** Convert the given character to its equivalent uppercase character. *)
type t = char
(** An alias for the type of characters. *)
val compare: t -> t -> int
(** The comparison function for characters, with the same specification as
{!Pervasives.compare}. Along with the type [t], this function [compare]
allows the module [Char] to be passed as argument to the functors
{!Set.Make} and {!Map.Make}. *)
