I typed "stty iutf8" after updating to the latest world and kernel and the
backspace key still seems to erase only one byte when erasing Russian
letters. For example, I compile this program:
#include <iostream>
#include <string>
int main()
{
std::cout << "Enter something: ";
std::string sentence;
std::getline(std::cin,sentence);
std::cout << sentence << std::endl;
}
And when running the program, I type something using Russian letters,
use the backspace key to erase some letters, hit enter, and what I see
on the screen is some garbage. My LANG variable is set to C.UTF-8.
