This library is a wrapper around the utf8proc library, providing information about Unicode code-points and performing operations (mappings) on Unicode atoms. The central predicate is unicode_map/3, mapping a Unicode atom to another Unicode atom using a sequence of operations. The predicates unicode_nfd/2, unicode_nfc/2, unicode_nfkd/2 and unicode_nfkc/2 implement the four standard Unicode normalization forms.
