Hi! This updates UP012 documentation to describe both supported cases: replacing ASCII literals with bytes literals and removing redundant explicit UTF-8 encoding arguments. It also handles the latter for general expressions such as
str(exc).encode("utf-8"), which the rule previously skipped.Fixes #26854
