I hope your compiler complains loudly about that code. You can't just
assign a wchar_t to a char and expect it to do anything sensible.
A short search points to std::wstring_convert, but that has been
deprecated in C++17, and it's not obvious to me what the replacement is.
There is always ICU, of course, but that feels like cracking a nut with
a sledgehammer.
Personally, I might roll my own if an hour of googling doesn't turn up
anything promising (UTF-8 encoding is quite simple), but that shouldn't
be necessary.
