val from_unichar : Glib.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 : Glib.unistring -> string

val to_unichar_validated : string -> pos:int Stdlib.ref -> Glib.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 Stdlib.ref -> Glib.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 -> Glib.unistring

to_unistring decodes an UTF-8 encoded string into an array of unichar. The string must be valid.
