This parameter is needed to provide compatibility between utf16_t and
utf32_t, so we may call this function from a single template for both
types.

Windows and Apple (NSString) are using UTF-16 wchar_t. All others use
UTF-32. This eliminates need for additional conversion should we need
UTF-32 on Windows&Apple or UTF-16 on others. Mind, UTF-16↔32 is not a
trivial conversion as it may change number of code units.

Since stdex::locale_default is inline, it is initialized by the first
module referencing it. Not necessarily compiled with the same _CONSOLE
definition as other modules. This makes the default locale fluid.

Brain-dead _Printf_format_string_ SAL doesn't understand utf32_t is good
enough for unsigned int expected by %x placeholder.

Each unit test .cpp file is not a separate compilation unit in Xcode project
like it is in Visual Studio. Hopefully, Visual Studio test tool still likes
this arrangement.

vsnprintf_l and vswprintf_l mutate va_list parameter on some versions of macOS (11.7 Big Sur).
This makes it impossible to call printf multiple times with a growing buffer.

Actually, using ill-created locale was the cause sprintf returned EILSEQ on %ls inserts containing emoji.

This allows same platform management across different operating systems.
Like with charset_id, the Windows numbering was adopted.

Microsoft declares all identifiers starting with underscore _ as
internal to MSVC. Thus, we should either use defined(DEBUG) or
!defined(NDEBUG) to distinguish Debug and Release builds.

While being here only for templates to work with various data types, the
one-byte "swap" functions are actually noop.
