The problem is not here. I can change the encoding of the command string 
(which is passed to external cygwin apps) using
coding-system-for-write. It works (converted correctly utf-8->cp1257, 
cp1251, etc), but it doesn't help, because of the way the args (command 
line) are passed/transcoded through the winapi (CreateProcessA) and 
cygwin layer.
This bug is related to bug#6705 (there are detailed description of 
what's happening)
