No such function [with exact results] exists anywhere (no matter the
programming language). The best programs can do is to interrogate the
contents of a file and make a best guess.  How they do that
interrogation -- I unfortunately don't know. I guess you could look at
the source code of some of the open source text editors and see what
they do. Some text editors are much better than others. eg: EditPad Pro
(commercial) and jEdit (open source) are very good at these interrogations.

Alternatively, simply ask the person that supplies you with these files
to tell you want encoding they use. They must know the answer.
