When the isBinary is true, then resulting object represents binary even if the value is valid utf-8 sequence, that is, its UnderlyingType should be Byte[]. On the other hand, when contrast, the isBinary is false, and if the value is valid utf-8, then the resulting object can be String, and its UnderlyingType should be String.
