Mangler

A collection of utilities to validate and transform strings with diacritics, unicode and ascii.

Substitute diacritics in the given string with their ASCII equivalents. This function works by performing NFD normalization on the graphemes in the string. It then removes any non-words from the string. Due to this, an allowlist must be provided to keep any non-word characters intact.

Also provides utility functions to validate if a string contains ASCII or Unicode characters
