when using set-buffer-file-coding-system
(emacs 23), i get the following choices with utf-8:
Possible completions are:
what is the "with-signature" mean? is it the unicode BOM marker?
and what about "emacs"? Is that the emacs 22's internal encoding system?
I got the answer. Just do list-coding-systems and result will answer with short description. Basically yes to both above.
