title: How to write text inside a rectangle in emacs artist-mode?
body: <p>I am learning artist-mode in emacs and finding it pretty interesting.</p>
  
  <p>I want to create shapes and write text inside them as we can do with other software where one can draw shapes.</p>
  
  <p>However, when I type some characters inside a rectangle, the shape gets distorted. The vertical line gets shifted by some characters. </p>
  
  <p>Please see attached image.

  <p>Is there something I can do to fix it? Or is it a bug in artist-mode. I watched some screencasts and videos and did not remember anyone mentioning anything about this odd behavior.</p>
  
  <p>I am on Mac and my emacs version is</p>
  
  <p>GNU Emacs 25.1.1 (x86_64-apple-darwin16.0.0, NS appkit-1504.00 Version 10.12 (Build 16A323))</p>
