 To use it, just include "utf8.h" or whatever the file name is at the current moment in time. I'll /probably (not)?/ update this in the future.
 
 CC0 because I don't deserve credit for how awful this is.

+Some example code because why not.

+Printing a string:
+```cpp
+#include <iostream>
+#include "utf8.h"

+int main() {
+  string32 test = "こんにちは！";

+Getting the third character of a string, without breaking UTF-8 strings.
+```cpp
+#include <iostream>
+#include "utf8.h"
+
+int main() {
+  string32 test = "こんにちは！";
+  std::cout << "The third character of `" << test << "` is: " << test[2] << "\n";

+  for (int i(0);i<test.size();i++)
