如何定义使用`replace-string`替换特定字符串的Emacs命令

我需要删除ascii字符0253，并在其中添加回车符。在emacs中我执行

I need to remove ascii character 0253 and add a carriage return in it's place. In emacs I do

M-x replace-string ý RET C-q C-j

Cq Cj添加回车符。我经常这样做，我创建一个自定义的defun会更好。

C-q C-j adds a carriage return. I do this often enough that I creating a custom defun would be much better.

这是我到目前为止

(defun remove-253 ()
   "Removes ASCII Character 0253 and adds a carriage return in it's place"
   (interactive)
   (replace-string "ý" .... not sure what to do next )
)

你的想法？

谢谢，
