Access to the Unicode Character Database, implemented as bindings to the International Components for Unicode (ICU) libraries.
Unicode assigns each code point (not just assigned character) values for many properties. Most are simple boolean flags, or constants from a small enumerated list. For some, values are relatively more complex types.
For more information see "About the Unicode Character Database" http://www.unicode.org/ucd/ and the ICU User Guide chapter on Properties http://icu-project.org/userguide/properties.html.

Working with character properties
The property
function provides the main view onto the Unicode Character
Database. Because Unicode character properties have a variety of types,
the property
function is polymorphic. The type of its first argument
dictates the type of its result, by use of the Property
typeclass.
For instance,
returns a property
Alphabetic
Bool
, while
returns a property
NFCQuickCheck
.Maybe
Bool

Functions
blockCode :: Char -> BlockCode Source #
Return the Unicode allocation block that contains the given character.
charFullName :: Char -> String Source #
Return the full name of a Unicode character.
Compared to charName
, this function gives each Unicode code point
a unique extended name. Extended names are lowercase followed by an
uppercase hexadecimal number, within angle brackets.
charName :: Char -> String Source #
Return the name of a Unicode character.
The names of all unassigned characters are empty.
The name contains only "invariant" characters like A-Z, 0-9, space, and '-'.
charFromFullName :: String -> Maybe Char Source #
Find a Unicode character by its full or extended name, and return its code point value.
The name is matched exactly and completely.
A Unicode 1.0 name is matched only if it differs from the modern name.
Compared to charFromName
, this function gives each Unicode code
point a unique extended name. Extended names are lowercase followed
by an uppercase hexadecimal number, within angle brackets.
charFromName :: String -> Maybe Char Source #
Find a Unicode character by its full name, and return its code point value.
The name is matched exactly and completely.
A Unicode 1.0 name is matched only if it differs from the modern name. Unicode names are all uppercase.
combiningClass :: Char -> Int Source #
direction :: Char -> Direction Source #
Return the bidirectional category value for the code point, which is used in the Unicode bidirectional algorithm (UAX #9 http://www.unicode.org/reports/tr9/).
isMirrored :: Char -> Bool Source #
Determine whether the code point has the BidiMirrored
property. This
property is set for characters that are commonly used in Right-To-Left
contexts and need to be displayed with a "mirrored" glyph.
Conversion to numbers
digitToInt :: Char -> Maybe Int Source #
Return the decimal digit value of a decimal digit character.
Such characters have the general category Nd
(decimal digit
numbers) and a NumericType
of NTDecimal
.
No digit values are returned for any Han characters, because Han
number characters are often used with a special Chinese-style
number format (with characters for powers of 10 in between) instead
of in decimal-positional notation. Unicode 4 explicitly assigns
Han number characters a NumericType
of NTNumeric
instead of
NTDecimal
.
