// 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.
