In C, as in C++, there is no ready-made solution for counting UTF-8 characters. You can convert UTF-8 to UTF-16 using mbstowcs and use the wcslen function, but this is not the best way for performance (especially if you only need to count the number of characters and nothing else).

I think a good answer to your question is here: counting unicode characters in c++.
