Issue #9642: Fix filesystem encoding initialization: use the ANSI code page on

Windows if the mbcs codec is not available, and fail with a fatal error if we
cannot get the locale encoding (if nl_langinfo(CODESET) is not available)
instead of using UTF-8.

- Issue #9642: Fix filesystem encoding initialization: use the ANSI code page
on Windows if the mbcs codec is not available, and fail with a fatal error if
we cannot get the locale encoding (if nl_langinfo(CODESET) is not available)
instead of using UTF-8.
