Sᴍᴀʟʟ ᴄᴀᴘɪᴛᴀʟ letters

In typography, small capitals (usually abbreviated small caps) are uppercase (capital) characters set at the same height and weight as surrounding lowercase (small) letters or text figures. They are used in running text to prevent capitalized words from appearing too large on the page, and as a method of emphasis or distinctiveness for text alongside or instead of italics, or when boldface is inappropriate.

As of Unicode 5.1, there are several small capitals missing. There's no small capital F, S, Q and X. S and X would be same as small small ones, so I've listed small ones instead of leaving their place empty.
