(** 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 OCaml.
All characters outside the ASCII printable range (32..126) are
escaped, as well as backslash, double-quote, and single-quote. *)
val lowercase : char -> char
[@@ocaml.deprecated "Use Char.lowercase_ascii instead."]
(** Convert the given character to its equivalent lowercase character,
using the ISO Latin-1 (8859-1) character set.
@deprecated Functions operating on Latin-1 character set are deprecated. *)
val uppercase : char -> char
[@@ocaml.deprecated "Use Char.uppercase_ascii instead."]
(** Convert the given character to its equivalent uppercase character,
using the ISO Latin-1 (8859-1) character set.
@deprecated Functions operating on Latin-1 character set are deprecated. *)
val lowercase_ascii : char -> char
(** Convert the given character to its equivalent lowercase character,
using the US-ASCII character set.

val uppercase_ascii : char -> char
(** Convert the given character to its equivalent uppercase character,
using the US-ASCII character set.

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}. *)
val equal: t -> t -> bool
(** The equal function for chars.
@since 4.03.0 *)
