Naughty String Validator
https://pypi.org/project/naughty-string-validator/I created a Python library with more than 300,000 downloads so far.
It returns naughty strings from an offline database of the Big List of Naughty Strings and emojis. The Big List of Naughty Strings is an evolving list of strings with a high probability of causing issues when used as user input data. It can be included in the test automation framework for API, UI, or database testing to validate them against naughty strings.
