Aa I already said NO. It is "undefined behaviour" for regexps but not
for constant strings.

Actually it's defined exactly for specific sequences for strings. It is not defined what happens on any others.

i.e. there's nothing stating that

\x -> \x


\x -> x

inside a string. It's not clearly defined there at all.
