25       type t
26
27
28       The type for Unicode characters.
29
30       A  value of this type represents a Unicode scalar value which is an in‐
31       teger in the ranges 0x0000 ...  0xD7FF or 0xE000 ...  0x10FFFF .

69       val succ : t -> t
70
71
72       succ u is the scalar value after u in the set of Unicode scalar values.
73

90       val is_valid : int -> bool
91
92
93       is_valid  n is true iff n is a Unicode scalar value (i.e. in the ranges
94       0x0000 ...  0xD7FF or 0xE000 ...  0x10FFFF ).
95
96
97
98       val of_int : int -> t
99
100
101       of_int i is i as a Unicode character.

108       val to_int : t -> int
109
110
111       to_int u is u as an integer.

130
131
132       to_char u is u as an OCaml latin1 character.
133
134
135       Raises Invalid_argument if u does not satisfy Uchar.is_char .
