-// From <https://en.cppreference.com/w/c/io/fwprintf#Notes>:
-//
-// While narrow strings provide snprintf, which makes it possible to determine
-// the required output buffer size, there is no equivalent for wide strings
-// (until C11's snwprintf_s), and in order to determine the buffer size, the
-// program may need to call swprintf, check the result value, and reallocate a
-// larger buffer, trying again until successful.
-//
-// snwprintf_s, unlike swprintf_s, will truncate the result to fit within the
-// array pointed to by buffer, even though truncation is treated as an error by
-// most bounds-checked functions.
