On Windows, in a C program there are several locale concepts
that not necessarily are synchronized. On one hand, there is the
system default ANSI code-page, which determines what encoding is used
for file names handled by the C library's functions and the Win32
API. (We are talking about the "narrow" functions here that take
character pointers, not the "wide" ones.)

On the other hand, there is the C library's current locale. The
character set (code-page) used by that is not necessarily the same as
the system default ANSI code-page. Strings in this character set are
returned by functions like <function>strftime</function>.
