For sure the Python tokenizer/parser should reject octal escapes that produce values >= 256. Certainly in bytes strings. Probably also in text strings (nobody using Unicode thinks in octal). This is ancient behavior though (it's the same in 2.7) so it may require a deprecation for the text string case. (For byte strings, it should become an error in 3.9 -- dropping the top bit is nonsensical.)

The regex parser should not be changed.
