As far as I know, there is no way to know for sure, under unix or windows (or
any os, even macos when creator isn't set).  Programs that want to figure it
out usually look for non-printable characters, and if there's a significant
number of them, assume it's binary.  This works pretty well, but can get
confused when the locale of the text file you're reading has a different idea
of what 'non-printable' is.
