How can I enter Unicode characters (e.g. ♥♦♣♠) when logging into Windows?

As far as I can tell, it is possible to put a ♥ character in a Windows user password. The problem is, when you get to the log on screen, how can this be typed?

As far as I can tell, any symbol that is of the form Alt+xyz, but the ♥ character for example is only Alt+3.

How can I type this character (and others like it) at logon?

Try Alt + number pad keys. This used to work on older versions of windows. I don't have windows 8 or a number pad to test this though – FDinoff – 2013-07-21T19:11:59.067

@FDinoff that is what I am doing now. It will not let me do Alt + single number – soandos – 2013-07-21T19:15:42.733

I'd advise against it, simply because being able to enter them is so iffy, and may well depend on the particular computer and browser version you're using. (But if you're using a computer that does not have the separate keypad, remember you need to do "Num Lock" before you type the key combo on the M-9 keys of the simulated keypad array.) – Daniel R Hicks – 2013-07-21T19:16:09.457

@DanielRHicks This is for windows login on a laptop. It will always have a num pad. – soandos – 2013-07-21T19:19:18.310

@soandos try padding with 0s? – FDinoff – 2013-07-21T19:19:48.493

@FDinoff, I tried. I think the zeros change the symbols though in general Ã├ (0963,963) – soandos – 2013-07-21T19:25:58.807

FYI alt-codes enter characters from your current codepage, not unicode. You need to set a flag in the registry to use unicode alt-codes.

On Windows 8 logon screen you just have to be really fast to type ♥ in password field. Don't hold the Alt for too long. I don't know how fast are your fingers, but you can probably forget about codes longer than 3 characters.

Besides those characters are obviously not supported I would not advice to use them, because they won't add as much entropy as you may expect.
