Sadly, this is true. The reason is that MinGW relies on the "obsolete"
C runtime MSVCRT.dll, which is terribly broken regarding multi-byte
support. Heck, I cannot even output a Chinese character by the
wide-char version putwc, and putc is broken too.

An old discussion is here:

The same program can work well on Windows XP by any compiler, but only
works if compiled with a runtime that is not MSVCRT.dll--i.e., static
runtime by MSVC 6 or later, or dynamic runtime by MSVC 7+. MinGW only
uses MSVCRT.dll, and the resulting binary cannot output multi-byte
characters reliably on Windows versions later than Vista.
