normal.py

Find unicode codepoints to use in normalisation and transformation attacks.

output is in the format:

replacement char -> char its replacing | codepoint of replacement -> codepoint of char its replacing | name : normalization format

Search for unicode codepoints that you can use to replace characters in a given string
