If DoubleByteString Class >> withAll: or DoubleByteString >> addAll:
is called with an argument of String or Symbol that is larger than
4048, the result will be corrupt.
CharacterCollection>>asDoubleByteString calls withAll:, so uses of
this method will also have this problem.
This bug does not affect cases where the argument is a
DoubleByteString or DoubleByteSymbol; for these the result is correct.
