title: Unicode character support
body: <p>Usually in C++ we use <code>wchar_t</code> and <code>wstring</code> for Unicode wide characters and strings. Do we have anything like this in C#? </p>
  
  <p>To make things simple let me put it this way:</p>
  
  <p>If I'm simply converting C++ code to C# so what should I use in place of <code>wchar_t</code> and <code>wstring</code> ?
  Any help will be appreciated.</p>
