[Bug c++/33852] New: incorrect text formating in "std::cout" with UTF-8

[siegerstein at pochta dot ru]

Here is incorrect text formating with using cout() with setw() in UNICODE
(UTF-8)
Two text: first in English - correct formating, second - russian in UTF-8 -
incorrect.

#include <iostream>
#include <iomanip>

int main() {
        std::cout.setf(std::ios::left);
        std::cout.fill('_');

        std::cout << std::setw(15) << "Mixer" << std::setw(15) << "Device" <<
std::setw(15) << "Recording" <<
                        std::setw(15)   << "Active" << std::setw(15) <<
"Stereo" << std::setw(15) << "Current" << std::endl;
        std::cout << std::setw(15) << "Channel" << std::setw(15) << 
"Available" << std::setw(15) << "Source" <<
                        std::setw(15)   << "Source" << std::setw(15) <<
"Device" << std::setw(15) << "Level" << std::endl;

std::cout << std::endl;

// Russian text in UTF-8
// Not correct formating text....

        std::cout << std::setw(15) << "Êàíàë" << std::setw(15) << "Äîñòóïíîñòü"
<< std::setw(15) << "Èñòî÷íèê" <<
                        std::setw(15)   << "Àêòèâíîñòü" << std::setw(15) <<
"Ñòåðåî" << std::setw(15) << "Òåêóùèé" << std::endl;
        std::cout << std::setw(15) << "ìèêøåðà" << std::setw(15) << 
"óñòðîéñòâà" << std::setw(15) << "çàïèñè" <<
                        std::setw(15)   << "èñòî÷íèêà" << std::setw(15) <<
"óñòðîéñòâî" << std::setw(15) << "óðîâåíü" << std::endl;

        return 0;
}
