Based on the [**`unicode`** package](https://hackage.haskell.org/package/unicode) by *Henning Thielemann*.



This library aims to provide functionality to make working with certain blocks of

unicode characters more effective.



Currently the package contains the following modules:



 - **`Data.Char.Core`**: a module that defines common data structures;

 - **`Data.Char.BallotBox`**: rendering boxes that are empty, with a checkmark, or a cross;

 - **`Data.Char.Block`**: rendering a 2-by-2 block by a matrix of `Bool`s;

 - **`Data.Char.Block.Sextant`**: render blocks that consists out of a 3 × 2 raster;

 - **`Data.Char.Brackets`**: determine if a character is a bracket, and find the corresponding bracket;

 - **`Data.Char.Braille`**: a module to render Braille characters with six or eight dot cells;

 - **`Data.Char.Card`**: a module to work with playing cards;

 - **`Data.Char.Chess`**: a module to render chess pieces (and some variants) in unicode;

 - **`Data.Char.Control`**: a module that visualizes *control characters*;

 - **`Data.Char.Combining`**: combine a character with a (sequence of) *combining* characters (diacritics, geometrical shapes, etc.);

 - **`Data.Char.Currency`**: translate currencies to Unicode characters and vice versa;

 - **`Data.Char.Dice`**: a module to render die unicode characters;

 - **`Data.Char.Domino`**: a module to render domino unicode characters;

 - **`Data.Char.Egyptian`**: a module that defines pattern synonyms for ancient Egyptian hieroglyphs;

 - **`Data.Char.Emoji.*`**: modules that provide functions to render *emoji* characters (flags, objects, persons, etc.);

 - **`Data.Char.Enclosed`**: functions to convert alphanumerical characters to characters where these are enclosed by circles, squares, parenthesis, etc.;

 - **`Data.Char.Frame`**: typesetting frame elements. Lines of the frames can be `Light` or `Heavy`, and there are additional options to use arcs for corners;

 - **`Data.Char.Math.*`**: a set of modules to render mathematical symbols and text, for example in *Fraktur*, *Blackboard bold*, etc.

 - **`Data.Char.Number.Duodecimal`**: a module to work with [duodecimal numbers](https://en.wikipedia.org/wiki/Duodecimal);

 - **`Data.Char.Number.Egyptian`**: a module to render [ancient Egyptian numerals](https://en.wikipedia.org/wiki/Egyptian_numerals);

 - **`Data.Char.Number.Mayan`**: a module to render [Mayan numerals](https://en.wikipedia.org/wiki/Maya_numerals);

 - **`Data.Char.Number.Roman`**: a module to render [Roman numerals](https://en.wikipedia.org/wiki/Roman_numerals);

 - **`Data.Char.Number.Segmented`**: a module to render numbers on a [seven-segment display](https://en.wikipedia.org/wiki/Seven-segment_display);

 - **`Data.Char.Number.Tally`**: a module to render [(Western) tally marks](https://en.wikipedia.org/wiki/Tally_marks);

 - **`Data.Char.Number.VulgarFraction`**: a module to use *vulgar fractions* defined in the Unicode standard;

 - **`Data.Char.Private`**: characters belonging to the *private usage area*;

 - **`Data.Char.Private.Klingon`**: Klingon script characters;

 - **`Data.Char.Small`**: making use of subscript and superscript in unicode, and for example formatting `Ratio` objects; and

 - **`Data.Char.Tag`**: a unicode block that is used as emoji modifiers for regional flags.



## `unicode-tricks` is *safe* Haskell



The modules are marked with the `{-# LANGUAGE Safe #-}` pragma, it thus provides

guarantees, for example about not using [`unsafePerformIO`](https://begriffs.com/posts/2015-05-24-safe-haskell.html).
