Thank you for watching the video and answering the question that I had from just reading the title.
Reversing a UTF-8 string is super hard in any language, rust doesn’t really make it that much harder.
In fact it is easy in rust. Might not be the most performance (or maybe it is), but you should be able to do just "my_str".chars().rev().collect::()
That chars() call hides a lot of complexity, but also even that might not be correct depending on what exactly you mean by “reversing a string”.

fun with flags (run it)
Actually
chars()is pretty simple - it's just UTF-8 decoding which is elegant and simple.The complexity is all around unicode, not UTF-8.
Based on the responses (i haven't watch the video), hu just revered according to Unicode codepoints (chars). Therefore this should do the same.
Of course chars() hides the complexity, that's what makes it easy.
