lower() and unaccent() (and most string functions) are not marked as leakproof. Is this due to possible locale / character encoding errors they might encounter?
I think you are partially correct. Its due to the fact that error messages, regardless of the root cause, result in the printing of the input value in the error message as context, thus exists a leak via a violation of “ It reveals no information about its arguments other than by its return value. ”
