Typically, backslashes are seen only as part of escape sequences. Therefore, the use of a backslash outside of a raw string or escape sequence
looks suspiciously like a broken escape sequence.
Characters recognized as escape-able are: abfnrtvox\'"
Noncompliant code example
s = "Hello \world."
t = "Nice to \ meet you"
u = "Let's have \ lunch"
Compliant solution
s = "Hello world."
t = "Nice to \\ meet you"
u = r"Let's have \ lunch" // raw string
