How to convert this macro to Elisp?

[kj]

I have a macro that I want to convert to Elisp.  Furthermore, I
want the resulting code to be completely non-interactive.

Here's what the macro looks like:

C-x RET c               ;; universal-coding-system-argument
euc-jp                  ;; self-insert-command * 6
RET                     ;; newline
C-x C-f                 ;; find-file
test                    ;; self-insert-command * 4
RET                     ;; newline
C-x RET f               ;; set-buffer-file-coding-system
utf-8                   ;; self-insert-command * 5
RET                     ;; newline
C-x C-s                 ;; save-buffer
raw-text                ;; self-insert-command * 8
RET                     ;; newline

How can I convert this to Elisp?

The last two lines of the macro above point to a potential wrinkle.
'raw-text<RET>' is my interactive response when Emacs asked what
to do about characters that it was unable to encode using the
requested encoding.  I imagine that in some cases this warning will
not appear, so this response would be unnecessary.

TIA!
