For example LaTeX files either use inputenc package to set encoding
(e.g. \usepackage[latin2]{inputenc}) or use magic first line to
specify TCX (TeX character translation) file 
(e.g. %& -translate-file=il2-t1).

Emacs encourages to use file variables, either in the form of magic
first line, or file variables at the end of file; I think the same
is true for Vim.


I'd like then for it to be at least as configurable as diff.*.funcname 
is for diff.

We can at least try to and check for UTF-16 magic first two bytes, and 
detect if we have character which is invalid in UTF-8 (for performance 
I guess checking only beginning of file)...

...and then falling back to fallback encoding, like gitweb does.
