This is the fault of the cygrunsrv tool, which still uses the
ANSI variants of the Win32 API.  The default codeset under Cygwin
is UTF-8, but that doesn't match your Windows ANSI codepage 1252,
so that's what probably goes wrong.

Cygrunsrv has to be changed to use the UNICODE variants of the
Windows Service API to get that working.
