title: Is there a wide character version of stat() (from sys/stat.h)?
body: <p>I have been using stat() for checking the existence of a file, which I understand is better practice than trying to open a file.
  However, stat() doesn't work for filenames containing unicode characters in other languages. Is there a wide character version of stat(), or something equivalent that I can use? </p>
  
  <p>If not, what is the next acceptable solution for checking existence of a file?</p>
