The unicode-data packages family

This repository provides packages to use the
Unicode character database (UCD):

• unicode-data for general character properties.
• unicode-data-names for characters names and aliases.
• unicode-data-scripts for characters scripts.
• unicode-data-security for security mechanisms.

The Haskell data structures are generated programmatically from the UCD files.
The latest Unicode version supported by these libraries is
15.1.0.

unicode-data

unicode-data provides Haskell APIs to efficiently
access the Unicode character database.
Performance is the primary goal in the design of this package.

Please see the
Haddock documentation
for reference documentation.

unicode-data-names

unicode-data-names provides Haskell APIs
to efficiently access the Unicode character names from the Unicode character
database.

Please see the
Haddock documentation
for reference documentation.

unicode-data-scripts

unicode-data-scripts provides Haskell APIs
to efficiently access the Unicode character scripts from the Unicode character
database.

Please see the
Haddock documentation
for reference documentation.

unicode-data-security

unicode-data-security provides Haskell APIs
to efficiently access the
Unicode security mechanisms database.

Please see the
Haddock documentation
for reference documentation.

Performance

unicode-data is up to 5 times faster
than base.

Unicode version in some major libraries

The following sections tracks the Unicode versions used in some major libraries.
While unicode-data packages do not depend on the Unicode version used in these
packages, there may be some mismatches when using them together.
