Windows console supports UTF-16LE UNICODE.
You can use some box-driving library like PDCurses for example.
Otherwise you can use the following approach
#include
#include
class output_swap {
output_swap(const output_swap&) = delete;
output_swap operator=(output_swap&) = delete;
public:
output_swap( ) noexcept:
prevCP_( ::GetConsoleCP() )
{
::SetConsoleCP( CP_WINUNICODE );
::SetConsoleOutputCP( CP_WINUNICODE );
}
~output_swap() noexcept {
::SetConsoleCP( prevCP_ );
::SetConsoleOutputCP( prevCP_ );
}
private:
::DWORD prevCP_;
};
void draw_text(const wchar_t* text)
{
static ::HANDLE _out = ::GetStdHandle(STD_OUTPUT_HANDLE);
::DWORD written;
::WriteConsoleW( _out, text, std::wcslen(text), &written, nullptr );
}
int main(int argc, const char** argv) {
output_swap swap;
draw_text(L"┏━━━━━━━━━━━━━━━━━┓\n");
draw_text(L"┃ OK ┃\n");
draw_text(L"┗━━━━━━━━━━━━━━━━━┛\n");
return 0;
}
Also check you console font, in the console settings. You are probably need a raster font, but this is also working for Consolas for example.
If you need console io streams, which can work with unicode as well as box driwing you can use my library
