Yes, it does (at least, os.open, os.stat support them, builtin open doesn't). > Are they encoded first before > passing to the Unicode APIs? Using what encoding? They aren't passed to the Unicode (W) APIs (by Python). Instead, they are passed to the "ANSI" (A) APIs (i.e. CP_ACP APIs). On Windows NT+, that API then converts it to Unicode through the CP_ACP (aka "mbcs") encoding; this is inside the system DLLs. CP_ACP is a lossy encoding (from Unicode to bytes): Microsoft uses replacement characters if they can, starting with similarly-looking characters, and falling back to question marks.
