If you want to reverse a string you run a bit of code that loops from the last character to the first - nomatter how its encoded
There's a lot of reasons why this general approach can result in gibberish Unicode. Combining diacritics, ligatures, RTL scripts

thats usually because of the variable word length - take UTF16 for example where each character is either 2 or 4 bytes
