    // Unicode can be a real pain in the neck. While UTF-8 encoding has become the de facto standard
    // encoding on Linux, macOS and the internet, some systems use other encodings, most notably
    // Windows which use UTF-16.
    // OpenXLSX is based on UTF-8. That means that all text input and output MUST be in UTF-8 format.
    // On Linux and MacOS, this will work out of the box because UTF-8 is baked into those systems.
    // On Windows, on the other hand, input and output must be converted to UTF-8 first. This includes
    // input strings that are hard-coded into your program. To stay sane, it is recommended that
    // all your source code files are in UTF-8 encoding. All major compilers and IDEs on windows
    // support UTF-8 encoded source files.
    // To convert input/output manually, you can use the Windows API, or 3rd party libraries, such
    // as Boost.NoWide.
    // In this example Boost.NoWide is used, as it provides some handy functionality that enables
    // console input/output with implicit conversion to/from UTF-8 on Windows.
