challenge

main.py

#!/usr/bin/python3 -S
flag = 'ictf{redacted}'
eval(input()[:8])

solution

Python performs NFKC normalization on identifiers before parsing them. Use this to write flag in three chars via the fl ligature. int() leaks the flag through stderr.

my solution (unintended)

{}[flag] leaks flag through stderr

in theory, 7 chars is the minimum here because of this
