If 'default-directory contains characters not encodable with local
language encoding(cp932 for Japanese Windows OS),
#'start-process fails to start subprocess.
For example, set 'default-directory to "c:/tmp/test丄" and 'M-x shell'
fails with the error message:
start-process: Spawning child process: Exec format error

This is a known limitation of starting subprocesses from Emacs on
Windows: we only support running them in directories and with
command-line arguments that can be encoded by the system codepage.
The reasons are explained in a large comment that starts around line
1570 of src/w32.c.
Sorry.
