fs readdir with buffer and file types problem #33348

• Version: 12.16.3
• Platform: linux64
• Subsystem: gentoo

What steps will reproduce the bug?

reading directory with files names using buffer as path does not work.

const fs = require('fs');
fs.readdir( Buffer.from( "."),{withFileTypes:true,encoding:"buffer"},(e,d)=>console.log("dir",d));

It works correct in version 12.14.0 but after upgrade it stopped to work.
using it without files types works:
// fs.readdir( Buffer.from( "."),{withFileTypes:false,encoding:"buffer"},(e,d)=>console.log("dir",d));

How often does it reproduce? Is there a required condition?

every time

What is the expected behavior?

get directory entries with file types i.e. array of Dirent objects

What do you see instead?

error message:

Uncaught:
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received an instance of Buffer

Additional information

This bug is degradation because it doesn't exists in version 12.14.0 and present in versions 12.16.1 and 12.16.3 at least.
I use buffer instead of string because working with my old archives with non utf-8 names.
