That doesn't solve the problem (try to pass utf-8 string from Emacs to 
cygwin/bin/(ba)sh.exe or any other cygwin app), nor it anyhow 
complicates the matter (cmdproxy just passes commandline to 
CreateProcess(); same happens in w32proc.c calling /bin/sh instead of 
cmdproxy.exe). The problem is not cmdproxy itself, but winapi/cygwin 
layer and the way the args are passed/transcoded using CreateProcess(A) 
-> cygwin layer.
