Unicode 6.0 has: 1F512 and 1F513 closed and open locks. Also 1F511 is a key, 1F510 is a key and lock, and 1F50F is a lock with ink pen(?). Unicode 6.0 also adds ffwd and rewind symbols but frustratingly leaves out pause and play. Plenty of triangles for play (which may or may not match the new additions). But two vertical lines or boxes are going to be very inconsistent from font to font in looking like a pause symbol. My biggest peeve? The standard power button symbol on every computer and almost everything else these days, the IEC 5009 standy icon, also recognized as the power symbol in IEEE 1621. You can approximate the IEC 5010 on/off button with some other things, but it won't reliably look the same, and won't look at all like the IEC 5009 icon. Pause, play, and power buttons are WAY WAY WAY more useful (i.e. necessary) in text than a nail polish icon.
