  // BIG FAT WARNING FOR Microsoft Visual Studio Users
  //
  // YOU NEED TO CONVERT THIS SOURCE FILE ENCODING TO UTF-8 WITH BOM ENCODING.
  //
  // Unfortunately MSVC understands that the source code is encoded as
  // UTF-8 only if you add useless BOM in the beginning.
  //
  // So, before you compile "wide" examples with MSVC, please convert them to text
  // files with BOM. There are two very simple ways to do it:
  //
  // 1. Open file with Notepad and save it from there. It would convert 
  //    it to file with BOM.
  // 2. In Visual Studio go File->Advances Save Options... and select
  //    Unicode (UTF-8  with signature) Codepage 65001
  //
  // Note: once converted to UTF-8 with BOM, this source code would not
  // compile with other compilers, because no-one uses BOM with UTF-8 today
  // because it is absolutely meaningless in context of UTF-8.
