title: POI's setColumnWidth -- character width?
body: <blockquote>
    <p><code>public void setColumnWidth(int columnIndex,
                      int width)</code></p>
    
    <p>Set the width (in units of 1/256th of a character width)</p>
  </blockquote>
  
  <p>1/256th the width of <strong>WHICH CHARACTER</strong>? Different characters have different widths. What am I missing here?</p>
