Finnish company TietoEVRY TTF font "", in which offensive, in the opinion of the authors, English expressions are declared and are replaced by neutral expressions or blurry spots. Of course, if you add the character 200C or 200B (zero width non-joiner or zero width space) to the text, and even an extra space or change the case, censoring does not work. The font is declared "open-source", but the specific license is not called, and from the source texts so far just a list of ligatures.
