The fixes for PLE2510, PLE2512, PLE2513, PLE2514, and PLE2515 add escape sequences to raw strings, which is an invalid change because raw strings don’t support escape sequences. The fixes should convert the raw strings to normal strings first.

I’m using Python 3.10 for this example because literal null characters are syntax errors in later versions.
