      Value::deserializeForSorter reads a byte from a buffer as a char, which may be signed, and then uses that char to construct a BinDataType value, which is implicitly an int. Since the largest BinDataType value is 128, the value must actually be handled as an unsigned char.

      The same error exists in JParse::binaryObject.
