COBCH2375 ENCODING value invalid for XML/JSON data type

The ENCODING clause contains an invalid encoding for the source XML/JSON.

In the following code, an encoding of 1208 is incorrect; for national items, the encoding should be 1200.

      $set nsymbol(national)
        01 i1.
           05 x1 pic x.
        01 i2 pic n(200).
        move n'{"i1":{"x1":"£"}}' to i2.
        json parse i2 into i1 encoding 1208.
