This is expected.  Emacs on Windows supports starting programs only if
the command-line arguments, including the program's file name, can be
encoded in the system's codepage.  According to this bug report, your
system codepage is 1252, and the file name you show cannot be encoded
using that codepage.

This is a limitation of how Emacs on Windows invokes programs, but the
root cause is that many programs that run on Windows only support the
current codepage, and cannot support UTF-8 due to Windows misfeatures.

Sorry.
