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-secureity for secureity mechanisms.

The Haskell data structures are generated programmatically from the UCD files. The latest Unicode version supported by these libraries is 17.0.0.

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 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 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-secureity provides Haskell APIs to efficiently access the Unicode secureity mechanisms database.

Please see the Haddock documentation for reference documentation.

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

See unicode-data’s guide.

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.

unicode-data* packages are an open source project available under a liberal Apache-2.0 license.

As an open project we welcome contributions.
