The sgml_unicode.hpp stores UTF-32 strings in
stdex::sgml_unicode_pair::unicode. Hence stdex::utf32_t should be used as
its datatype. Unfortunately, that doesn't work with U string literal: U
requires hundreds of typecasts to make it fit stdex::utf32_t, since char32_t
is signed, stdex::utf32_t is unsigned. OTOH, L string literal cannot be
used on Windows (produces UTF-16, not UTF-32).

Looks short and compact, but requires static_cast<unsigned int> to cover T1
and T2 of different signess. Which doesn't look all that nice anymore.
However, typecasting would only hide the warning. We want the warning to
occur, to encourage us to sync types on template invocation instead.

AOsn is measuring time in **milli**seconds. Not **micro**seconds! All
conversions among clocks were off by a factor of 1000.

Unlike Posix, Windows handles HANDLE (file, pipe) and SOCKET descriptors
differently. It uses different close(), different errno... So sys_object
was not usable for socket without templating operations to a traits
class.

It's useful to clone std handles when creating streams to write/read to
standard streams. As the stream we give handle to assumes the handle
ownership, it'd close the std handles in stream destructor.

MSVC fails to deduce character type from std::string/wstring when
converting to std::basic_string_view.

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.

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.

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.
