"""**Token Smuggling**

Probes that attempt to bypass filters via obfuscation of contentious terms.

This module is suitable for probes that work using token/ASCII smuggling.

Token smugging attacks attempt to hide malicious content among benign text, in a way that bypasses alignment but is still reacted to by the target. This might involve swapping letters out for unusual unicode representations of the same letters, including meta-tokens like a zero-width space in order to break up the malicious text, or other encoding tricks.
