At the time of SetB/GetB there might not even been Unicode type in J, since then there's now UTF-8 possibility over discarding upper byte. For example,
SetB COM -> J BYTE[] Literal array (as is) BSTR Literal array (as UTF-8) GetB COM <- J BSTR Literal array (as UTF-8) BSTR Unicode Set COM -> J BYTE[] Literal array (as is) BSTR Unicode Get COM <- J BYTE[] Literal array (as is) BSTR Unicode (Or something similar, but having ability to pass Unicode and UTF-8 without losing upper bytes.) Arrays of BSTRs could be mapped to arrays of boxed strings. (Same as arrays of VARIANTs are recursively boxed.) Because this is a frequent thing and different from the latter.
