Description:
Generator and shrink functions for testing Unicode-related software.
The default Arbitrary instance for the Char type intentionally generates only ASCII values. This can lead to a false sense of security in cases where Unicode compliance is required, as encodings that span multiple bytes or code units will simply not be exercised at all. . This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
