  <p>I have a TextView where I'm showing some report data. I use a monospace TypefaceSpan for a portion of it because I want columns to line up.</p>
  
  <p>I used my test Android device to figure out how many columns I could fit, but the Android emulator seems to have exactly one less column, which makes things wrap in an ugly way in portrait mode.</p>
  
  <p>Is there a way to find out how many characters should fit on 1 line?</p>
