title: ANSI escape sequences aren't printed to stdout on Windows
body: <p>I'm trying to write an ANSI escape sequence to stdout using node.js on Windows, but it does not appear to work.</p>
  
  <p>Specifically, I use <a href="http://conemu.github.io/" rel="nofollow">ConEmu</a> which does <a href="http://conemu.github.io/en/AnsiEscapeCodes.html" rel="nofollow">support</a> a subset ANSI codes.  I've created a test file which should rename the current console tab:</p>
  
  <pre><code>process.stdout.write('\x1b]9;3;"abc"\x1b\x5c');
  </code></pre>
  
  <p>However, nothing happens when I run it.  If I run <code>node test &gt; out.txt</code>, the correct bytes are written to the output file.</p>
  
  <p>Why don't the escape sequences work?</p>
