title: Is there a Unicode glyph that looks like a "key" icon?
body: <p>Unicode has a million icon-like glyphs, but they're not always easy to search by, since I don't always know what they look like.</p>
  
  <p>Is there a Unicode glyph that looks like a "key"?  Or is there a symbol that's used in database circles to mean "primary key", which <em>is</em> in Unicode?</p>
