The only way it works is when i set LANG process-environment variable to 
the current windows locale codepage and 'coding-system-for-write' to the 
encoding/charset in which i'd like to grep.
That way it works, but i'm not sure (seriously doubt) if LANG/locale 
codepage, which differs from the actual args encoding, won't result in 
any ugly problems/bugs (e.g. sorting, piping to other apps)
If it really won't and this setup is "as it should be, intended", then 
this bug could be closed.
