// 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.
