Note that this works only if "filename" is the file name expressed in
the "system codepage" encoding, though. File names in Windows are in
Unicode, and it is perfectly possible, and in some locales might even
be quite common, to have files and directories with names that can't
be expressed in the system codepage. (Example: Hebrew file names in an
Arabic localisation of Windows, Greek file names in a German
localisation of Windows.)

So in the remote chance that you plan to use code like this for some
functionality that somebody might find useful to prevent from working
properly on purpose, be prepared: Creating files with arbitrary
Unicode names isn't hard.

To work in general, you should handle file names in Unicode (typically
either UTF-16, which is the encoding that Windows itself and the
Microsoft C/C++ library use for their wide-character API, like
GetFileAttributesW() or _wfopen(), or UTF-8, which is what much open
source software uses, and then convert to/from UTF-16 for Windows and
C library wide-character API calls).
