SDL_iconv_wchar_utf8 - Convert a wchar_t string to UTF-8.

       This macro is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                            SDL_iconv_wchar_utf8(3)

       This is a helper macro that might be more clear than calling

       SDL_iconv_string
        directly.  However,  it  double-evaluates  its  parameter, so do not use an expression with side-effects
       here.
