How can I get "WHITE SMILING FACE (U+263A)" with the keyboard?

"In Windows you can:

Left Alt + 1 : ☺

But the number must be from the Numeric Keypad

You can also:

Left Alt + 2 : ☻
Left Alt + 3 : ♥
Left Alt + 4 : ♦
Left Alt + 5 : ♣
Left Alt + 6 : ♠
Left Alt + 7 : •
Left Alt + 8 : ◘
Left Alt + 9 : ○
Left Alt + 10 : ◙
Left Alt + 11 : ♂
Left Alt + 12 : ♀
Left Alt + 13 : ♪
Left Alt + 14 : ♫
Left Alt + 15 : ☼
Left Alt + 16 : ►"

its really fun to make the white smiley and it's really easy once you know how to make a white smiley. All you have to do is click the left alt and click the number 1 one the number pad thing.☺ and there you go, you get a white smiley.
