Description

QuickCheck Generator and shrink functions for testing software that uses Unicode data.

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 module deliberately avoids using the text and bytestring packages to avoid pulling in extra dependencies.

Synopsis

Newtype wrapper for convenience

data Unicode a #

A wrapper for Char and String, for which the Arbitrary instance generates full-Unicode characters.
