How to type smiley face ASCII☺?

The easiest way is to use the windows program charmap.

Just type charmap into the search box on the start menu (vista and 7) or select start->run and type in charmap (in 9x to XP).

Make sure the character set is set to Unicode in the dropdown in the lower half, and take your pick from the myriad of characters there. You can then copy and paste the characters to your heart's content.

NB: Not all websites will support Unicode text and may filter it out or complain at you.

Alt + 1 (on the number pad, make sure num lock is on) ☺

(alt+2 to make him black) ☻

Press CtrlShiftU, 2, 6, 3, A, Enter in order.
