In the status bar, the closest available option is to show the selected file's Description using the {sel:desc} code.
But that will show other information as well (e.g. image dimensions), will only report the encoding when a UTF Byte Order Mark appears at the start of the file (we try to avoid guessing encodings, as there is no reliable way to do so), and won't report the line endings. It probably won't be what you need.
I'm not sure if there is a good, performant way to get that information into the status bar. Displaying it as a column in the file display would be easier, if that's a useful alternative.
