unichar = int
type
unistring = unichar array
val from_unichar : unichar -> string
from_unichar 0xiii
converts a code point
iii
(usually in hexadecimal
form) into a string containing the UTF-8 encoded character
0xiii
. See
unicode.org for charmaps.
Does not check that the given code point is a valid unicode point.
val from_unistring : unistring -> string
val to_unichar_validated : string -> pos:int Pervasives.ref -> unichar
to_unichar_validated
decodes an UTF-8 encoded code point and checks
for incomplete characters, invalid characters and overlong encodings.
Raises Convert.Error
if invalid
val to_unichar : string -> pos:int Pervasives.ref -> unichar
to_unichar
decodes an UTF-8 encoded code point. Result is undefined
if pos
does not point to a valid UTF-8 encoded character.
val to_unistring : string -> unistring
to_unistring
decodes an UTF-8 encoded string into an array of
unichar
. The string must be valid.
val first_char : string -> unichar
first_char
returns the first UTF-8 encoded code point.
val next : string -> pos:int -> int
next
returns the position of the code point following the one at pos
.
val length : string -> int
length
returns the number of code-points in the UTF-8 encode string
