`for await (const c of process.stdin)` does not accept EOF in Windows

Version

v24.13.0

Platform

Microsoft Windows NT 10.0.26200.0 x64

Subsystem

No response

What steps will reproduce the bug?

1. Run node -e "for await (const c of process.stdin) console.log(c)"
2. [f] [o] [o] [Enter]
3. [Ctrl] + [Z] or [Ctrl] + [D] (= EOF)
4. [Enter]

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

Always

What is the expected behavior? Why is that the expected behavior?

In Ubuntu and Alma Node successfully stop reading by Ctrl + D:

$ node -e "for await (const c of process.stdin) console.log(c)"
foo
<Buffer 66 6f 6f 0a>

What do you see instead?

Node will never stop reading in spite of [Ctrl] + [Z] or [Ctrl] + [D]:

PS> node -e "for await (const c of process.stdin) console.log(c)"
foo
<Buffer 66 6f 6f 0d 0a>
^Z
<Buffer 1a 0d 0a>
^D
<Buffer 04 0d 0a>

I had to end up with killing the process by Ctrl + C.

Additional information

I usually use Proto to manage Node versions, but it was able to be reproduced in the portable version in the official zipball:

PS> .\Downloads\node-v24.13.0-win-x64\node -e "for await (const c of process.stdin) console.log(c)"
foo
<Buffer 66 6f 6f 0d 0a>
^Z
<Buffer 1a 0d 0a>
^D
<Buffer 04 0d 0a>

PS> echo $?
False

(ended up with Ctrl + C)

Workaround: insert if ((c[0] === 4 || c[0] === 0x1a) && c.length === 1 + EOL.length && c.toString("latin1", c.length - EOL.length) === EOL) break; (import { EOL } from "node:os")

If this bug did not exist, you would be able to retrieve the entire multiline text from stdin by (await Array.fromAsync(process.stdin)).join("") in all platforms.

Start by reproducing the issue with the reported node -e "for await (const c of process.stdin) ..." command on Windows and trace the process.stdin async-iteration entry point. Done means Ctrl+Z or Ctrl+D is recognized as EOF, the loop terminates, and the behavior is covered by a Windows regression test.
