Subject: bug#61934: 28.2; Exec format error when `default-directory` contains non-ASCII characters on Windows 11
Date: Fri, 03 Mar 2023 14:56:32 +0100

Calling external commands fails on Emacs under Windows 11 if
`default-directory' contains non-ASCII characters. Steps to reproduce:

0. Start emacs -Q
1. Create directory C:/zażółćgęśląjaźń.
2. Enter the directory with dired.
3. Press M-! and try executing any command.
4. Minibuffer shows error message: "Spawning child process: Exec format error"

This is on Emacs build downloaded from
gnu.org/software/emacs/.

Best regards,
