Unicode characters.
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 : tmin is U+0000.
val max : tmax is U+10FFFF.
val bom : tbom is U+FEFF, the byte order mark (BOM) character.
val rep : trep is U+FFFD, the replacement character.
succ u is the scalar value after u in the set of Unicode scalar values.
Invalid_argument if u is max.
pred u is the scalar value before u in the set of Unicode scalar values.
Invalid_argument if u is min.
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 -> tof_int i is i as a Unicode character.
Invalid_argument if i does not satisfy is_valid.
val to_int : t -> intto_int u is u as an integer.
val is_char : t -> boolis_char u is true iff u is a latin1 OCaml character.
val of_char : char -> tof_char c is c as a Unicode character.
val to_char : t -> charto_char u is u as an OCaml latin1 character.
Invalid_argument if u does not satisfy is_char.
val hash : t -> inthash u associates a non-negative integer to u.
