Module Ppx_deriving_runtime.Uchar

Unicode characters.

  • since 4.03
type t

The type for Unicode characters.

A value of this type represents a Unicode scalar value which is an integer in the ranges 0x0000...0xD7FF or 0xE000...0x10FFFF.

val min : t

min is U+0000.

val max : t

max is U+10FFFF.

val bom : t

bom is U+FEFF, the byte order mark (BOM) character.

  • since 4.06.0
val rep : t

rep is U+FFFD, the replacement character.

  • since 4.06.0
val succ : t -> t

succ u is the scalar value after u in the set of Unicode scalar values.

val pred : t -> t

pred u is the scalar value before u in the set of Unicode scalar values.

val is_valid : int -> bool

is_valid n is true iff n is a Unicode scalar value (i.e. in the ranges 0x0000...0xD7FF or 0xE000...0x10FFFF).

val of_int : int -> t

of_int i is i as a Unicode character.

val to_int : t -> int

to_int u is u as an integer.

val is_char : t -> bool

is_char u is true iff u is a latin1 OCaml character.

val of_char : char -> t

of_char c is c as a Unicode character.

val to_char : t -> char

to_char u is u as an OCaml latin1 character.

val equal : t -> t -> bool

equal u u' is u = u'.

val compare : t -> t -> int

compare u u' is Stdlib.compare u u'.

val hash : t -> int

hash u associates a non-negative integer to u.
