POSIX has no such encoding requirement on the |path| argument:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/open.html

on Linux, that buffer is a standard NUL-terminated C string which is passed 
directly to the kernel which more or less passes it directly to the fs driver.  
how some FS drivers interpret that string depends on the FS.
