I have a string in which there can be characters of both English and Russian alphabets, and it is not quite clear to me how to count the number of characters in such a string.

string test = "ТестTest"; cout << test.length();

As you know, in the output stream we get not the number of characters, but the number of bytes, that is, not 8, but 12. And I would like to somehow find out exactly the number of characters. What is the correct solution for this situation?

    The easiest option is to use wider strings to fit the character into one element. Example:

     #include <string> #include <iostream> int main() { std::wstring test = L"ТестTest"; std::wcout << test.length(); }

    Conclusion :

     8

    A better option is to use the appropriate external libraries to support Unicode , for example, ICU .
