bidirectional-unicode (PLE2502)#

Derived from the Pylint linter.

What it does#

Checks for bidirectional unicode characters.

Why is this bad?#

The interaction between bidirectional unicode characters and the surrounding code can be surprising to those that are unfamiliar with right-to-left writing systems.

In some cases, bidirectional unicode characters can also be used to obfuscate code and introduce or mask security vulnerabilities.


s = "א" * 100  #  "א" is assigned
print(s)  # prints a 100-character string
