> MetadataTypedColumnsetSerDe and DynamicSerDe should escape some special characters like
'\n' or the column/item/key separator.
> Otherwise the data will look corrupted.
> We plan to deprecate MetadataTypedColumnsetSerDe and DynamicSerDe for the simple delimited
format, and use LazySimpleSerDe instead.
> So LazySimpleSerDe needs to have the capability of escaping and unescaping.
