Strings are either handled by descriptor, which has the physical length,
or are assumed null terminated. User data is always passed by
descriptor because strings in the ODS are not null terminated. All
metadata strings are assumed null terminated.

JString (like the Microsoft CString) is set by assignment from either a
null terminated string or another JString (CString). Neither cares in
the least about the number of logical characters, nor should they.
Collation driven comparisons should be handled by higher level
facilities. The lower level string class is primarily concerned with
hold, passing, sharing, and deleting strings.
