Remove invisible characters in TXT

Characters like zero-width spaces (ZWSP), soft hyphens, or bidirectional control characters can be inserted into text without being visible to humans but still interpreted by machines. This method can be exploited in AI prompts to inject hidden instructions, manipulate outputs, or bypass security filters.

Deep CDR can efficiently detect and neutralize such attacks by cleansing the input and ensuring only legitimate content is processed.
