> "reversing a string" is no longer possible or meaningful. If you really wanted to, you could write a string reversal algorithm that treated two-character emojis as an indivisible element of the string and preserved its order (just as you'd need to preserve the order of the bytes in a single multi-byte UTF-8 character). You'd just need to carefully specify what you mean by the terms "string", "character" and "reverse" in a way that includes ordered, multi-character sequences like flag emojis. |
