title: PHP output showing little black diamonds with a question mark
body: <p>I'm writing a php program that pulls from a database source. Some of the varchars have quotes that are displaying as black diamonds with a question mark in them (�, <a href="http://www.fileformat.info/info/unicode/char/fffd/index.htm" rel="noreferrer">REPLACEMENT CHARACTER</a>, I assume from Microsoft Word text).</p>
  
  <p>How can I use php to strip these characters out?</p>
