Here is an updated version of the patch.
I use direct conversion in pgwin32_toUTF16() if a corresponding codepage
is available. If not available, I still use double conversion.
Now pgwin32_toUTF16() is exported from mbutil.c. I used the function
in following parts, although the main target of the patch is eventlog.
* WriteConsoleW() - write unredirected stderr log.
* ReportEventW() - write evenlog.
* CreateFileW() - open non-ascii filename (ex. COPY TO/FROM 'mb-path').
This approach is only available for Windows because any other platform
don't support locale-independent and wide-character-based system calls.
Other platforms require a different approach, but even then we'd still
better have win32-specific routines because UTF16 is the native encoding
in Windows.
