title: Is TCHAR still relevant?
body: <p>I'm new to Windows programming and after reading the Petzold book I wonder: </p>
  
  <p>is it still good practice to use the <code>TCHAR</code> type and the <code>_T()</code> function to declare strings or if I should just use the <code>wchar_t</code> and <code>L""</code> strings in new code?</p>
  
  <p>I will target only Windows 2000 and up and my code will be <a href="http://en.wikipedia.org/wiki/Internationalization_and_localization" rel="noreferrer">i18n</a> from the start up.</p>
