title: In what 8-bit character set is 0x9d meaningful?
body: <p>In what 8-bit ASCII-like character set for English is <code>0x9d</code> meaningful? 
  I'm cleaning up some old data files, and occasionally finding a <code>0x9d</code> in otherwise-ASCII text. (No, it's not UTF-8.)</p>
  
  <p>It's not valid in Windows-1252. The Python "latin-1" codec translates it to Unicode 0x9D, which is <a href="http://fileformat.info/info/unicode/char/009d/index.htm" rel="noreferrer">"Operating System Command"</a>. That makes little sense. In Unicode you get a box with [009d]. (In Python, you can convert anything to Latin-1 without errors being raised, but that doesn't mean it's meaningful to do so.)</p>
  
  <p>Examples, with Python-type escapes, from a messy database I'm cleaning up that combines text from many sources:</p>
  
  <pre><code>Guitar Pro, JamPlay, RedBana\\\'s Audition,\x9d Doppleganger\x99s The Lounge\x9d or Heatwave Interactive\x99s Platinum Life Country,\\"
  
  for example \\"I\\\'ve seen the bull run in Pamplona, Spain\x9d.\\" Everything
  
  Netwise Depot is  a \\"One Stop Web Shop\\"\x9d that provides sustainable \\"green\\"\x9d living
  
  are looking for a \\"Do It for Me\\"\x9d solution
  </code></pre>
  
  <p>From the context, I'd suspect ™ or ®. But what 8-bit code had those?</p>
