I don't think you can tell (certainly not easily) what the real user's
permissions are on a file without a lot of work. access is almost never the
right tool for the job (most of the time euid == ruid), but when it is the
right tool it's a lot better than the alternative.
I say backport. If people were trying to call os.access with unicode
filenames it would have been failing and they were either avoiding unicode
filenames as a result or working around it some other way. I can't see how
making os.access work with unicode filenames is going to break existing
code.
