Content
The documentation for `re.sub` states that "Unknown escapes such as ``\&`` are left alone.". This is only true for escapes which are not ascii characters, as far as I can tell (c.f. source on https://github.com/python/cpython/blob/master/Lib/sre_parse.py#L1047). Would there be value in amending that documentation to either remove that sentence or to clarify it? If so, I'm happy to submit a PR on GitHub.
