Sorry the previous post was sent without careful revise.

Octave gui editor only handles utf-8 and multibyte characters are also handled 
by utf-8. 
The command window on MS-windows does not handle uff-8 mode on windows command 
console without any treatment. For example, in Japanese version windows, the 
command window will open with code page 932 (Shift-JIS. Shift-JIS is 
traditional Japanese encoding on windows (from MS-DOS). )

However, the command console on windows supports utf-8 by code page 65001.  


Then from octave command prompt, "system('chcp 65001')" changes code page of 
windows console.
(chcp: is a command which CHange(s) Code Page of console windows. )

I have reported the issues on https://savannah.gnu.org/bugs/?44538.
 
The situation is improved on version up from 4.0.0-rc1 to rc2.
However the situation on rc3 became back the same as that on rc3.
 
What happens between upgrade rc2 and rc3?
 
I wonder why improvement is lost on rc3

Please come and discuss on the bug tracker.
