Imagine, if you will. A world where string reverse changes the character codes of the string.
What beauty, what wonder would such a world have?

Has someone made a library for that?
Use a dynamically typed language and you won’t have to: just override the default
reverse()method on strings like a Real Programmer!Unintended consequences you say? Nonsense! What could possibly go wrong?
I’m tempted to publish an NPM package to do so as a joke, but I fear that it’d get used seriously
