That sounds to me like you are hit by one of the following bugs:

Unfortunately, there is not much you can do to restore the command window 
(besides restarting Octave) because the conhost process which is used for the 
command window on Windows has crashed.
I'm hoping that this will no longer be an issue if or when the command window 
widget has been replaced with a cross-platform implementation. See:

If I understood correctly, jwe already did some preparatory changes for this on 
the development branch. So maybe it could be ready for Octave 7.

For the moment, try to avoid entering non-ASCII characters in the command 
window on Windows (running a script containing valid(!) non-ASCII characters 
seems to be fine afaict).

Another workaround might be to only use the bytes of your byte stream that 
might actually be ASCII text:
A;  % a variable containing a byte stream
char(A(A>31 & A < 128))

Hope this is still helpful
