Use buffer-file-coding-system.
If this is an interactive command, you could also use
select-safe-coding-system, which calls find-coding-systems-region
internally, and also has complex logic for finding suitable callbacks
and asking the user to select an encoding if it fails to find
something suitable. But this is not appropriate in non-interactive
code.
