Describe the problem The characters following the backslashes are not recognized as valid escape sequences. To include a literal backslash in a string, one would need to escape it by using two backslashes (\). This is just a warning, but we should fix it though, I think.

Step To Reproduce Still a bit puzzled. I was able to reproduce it in a docker container, but not on my OS.
