title: What characters are NOT present in Unicode?
body: <p>I have heard that some characters are not present in the Unicode standard despite being written in everyday life by populations of some areas. Especially I have heard about recent Chinese first names fabricated by assembling existing characters parts, but I can't find any reference for this.</p>
  <p>For instance, the character below is very common for 50 million people, yet it was <a href="http://en.wikipedia.org/wiki/Hokkien#Computing" rel="nofollow noreferrer">not in Unicode</a> until <a href="https://www.unicode.org/Public/UCD/latest/ucd/DerivedAge.txt" rel="nofollow noreferrer">October 2009</a>:</p>

  <p>Is there a list of such characters? (images, or website listing such characters as images)</p>
