I have a Windows-specific patch for open(), attached for reference.
But we need to consider about other issues:
- We need to consider about not only only open(), but also opendir(),
stat() and symlink().
- An entirely-different fix is needed for non-Windows platforms.
Probably we will convert encodings from GetDatabaseEncoding() to
GetPlatformEncoding() in MBCS, but this is not needed on Windows.
We should consider avoiding random ifdef blocks for the switching.
- Those conversions are not free. We might need to avoid conversions
for paths under $PGDATA because we only use ascii names in the server.
I used a test with IS_HIGHBIT_SET in the attached patch, but I'm not
sure whether it is the best method.
