This module implements Unicode (actually ISO-UCS) characters. All 31-bit code points are allowed.

Note For conversions to lower/upercase, see modules UTF8 and Rope.

val is_whitespace : CamomileLibrary.UChar.t -> bool

Determine if a character is a whitespace.

A character is a whitespace if it is either one of the ASCII whitespaces (characters 9, 10, 12, 13, 26 and 32), or a part of Unicode category Z (separators).

val is_uppercase : CamomileLibrary.UChar.t -> bool

Determine if a character is an uppercase character.

val is_lowercase : CamomileLibrary.UChar.t -> bool

Determine if a character is an lowercase character.

val is_newline : CamomileLibrary.UChar.t -> bool

Determine if a character is a newline. Newline characters are characters 10 ('\r'), 13 (\'n') and characters which are part of Unicode category `Zl

val lowercase : CamomileLibrary.UChar.t -> CamomileLibrary.UChar.t

Convert the given character to its equivalent lowercase character.

val uppercase : CamomileLibrary.UChar.t -> CamomileLibrary.UChar.t

Convert the given character to its equivalent uppercase character.

Conversion functions

val to_char : CamomileLibrary.UChar.t -> char

to_char u returns the Latin-1 representation of u.
Raises Out_of_range if u can not be represented by Latin-1.

val of_digit : int -> CamomileLibrary.UChar.t

Return the character representing a given digit.
Raises Invalid_argument "UChar.of_digit" if the argument is outside the range 0--9

val to_int : CamomileLibrary.UChar.t -> int

Alias of uint_code

Comparaison

val icompare : CamomileLibrary.UChar.t -> CamomileLibrary.UChar.t -> int

Compare two unicode characters, case-insensitive.
