Details:

After executing char([194 160]) all subsequent commands result in the >>
prompt only.  The workspace window does show the proper result.
Here is a test case:

 variable = 12
 whos variable
 char(194)
 whos variable
 char(160)
 whos variable
 char([194 160])
 whos variable
 variable = 13
 whos variable


results:
>> variable =  12
Variables in the current scope:

   Attr Name          Size                     Bytes  Class
   ==== ====          ====                     =====  =====
        variable      1x1                          8  double

Total is 1 element using 8 bytes

ans = �

>>
Note that only three of the five whos commands get a result.

Note: I found this on version 5.1.0 but checked version 4.2.2 and 4.4.1 with
the same result.
Also plotting does create a valid plot.
