I have 3 versions of octave installed on a windows machine for testing. For
octave 5.2, the following command returned no error

octave:1> unicode2native('test')
ans =

  116  101  115  116


however, the same command failed on 7.3 and 8.2, complaining the optional
parameter codepage is missing. 



octave:1> unicode2native('test')
error: unicode2native: CODEPAGE must be a string
error: called from
    unicode2native at line 63 column 5



from the latest documentation, codepage input is optional - same as matlab's
counterpart

https://docs.octave.org/v8.2.0/String-encoding.html

I consider this as a regression, and would be appreciated if this can be fixed
- as it now breaks my code working for both matlab and octave.


by the way, it appears that a previously reported bug #60480
(https://savannah.gnu.org/bugs/?60480)  has been fixed at least based on my
test (see screenshot)
