title: Can't open the desktop app created with PyInstaller
body: <p>I created a PyIinstaller file from a <code>.py</code> file. In this file, I've got files with the <code>.ui</code> extension created using PyQt4. But when I try to execute the file created, it shows this error:</p>
  
  <pre><code>File "C:\Users\Flosh\Desktop\dist\ProgramNew\New.exe", line 1
  SyntaxError: Non-ASCII character '\x90' in file C:\Users\Flosh\Desktop\dist\ProgramNew\New.exe on line 1, 
  but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
  </code></pre>
  
  <p>In the original <code>.py</code> file, I use the UTF-8 encoding, but this error shows an ASCII problem.</p>
  
  <p>How can I fix this error?</p>
