digitalmars.D.learn - readln of german Umlaute (terminal.d) / readln)

Hi,

I want to read passwords from the console (should be work on 
windows / linux / macos).
Adam Ruppe has a quite nice library (terminal.d) which allows to 
deactivating the echo to the console, which makes sense for 
passwords.

But I do not get it working with terminal.d nor with std.stdio: 
readln if it comes to special characters like ö.

The password is saved to a file.
readln will save for "ööö": "x94x94x94\n"
terminal.d will save: CCHCCHCCH

Changing the code page (CHCP 65001) will lead to the effect that 
empty strings are saved for both (readln, terminal.d)

Does someone already solved this problem and has a solution 
working on all operation systems?

Kind regadrs

Do you have a little test program I can copy/paste?

I suspect this is because I called ReadConsoleInputA instead of W 
for some weird reson..

- Here is what I use in one of my tools... and I never had 
problems with German password so far ;)

string getPassword(char mask = '*')
{
	import std.stdio;
	import libs.terminal;
	auto term = Terminal(ConsoleOutputType.linear);
	auto input = RealTimeConsoleInput(&term, ConsoleInputFlags.raw);
	string pass;
	dchar ch;
	ch = input.getch();
	while(ch != '\r' && ch != '\n')
	{
		import std.range;
		if(ch == '\b' && !pass.empty)
		{
			pass = pass[0..$-1];
			write('\b');
			stdout.flush;
		}
		else
		{
			pass ~= ch;
			write(mask);
			stdout.flush();
		}
		ch = input.getch();
	}
	return pass;
}

Thank you Adam. The ascii thing was causing the issue in the 
windows console.
Now it is working fine.

Kind regards
