> UniformRangePartition plays a role to divide a given range into multiple sub
> ranges. It is used for range shuffle.
> When UniformRangePartition divides a range of text fields, it Internally
> transforms arrays of bytes into unsigned integer. But, a byte represent -127
> to 127, and unicode is out of range in byte representation. So, the current
> approach can cause errors in this case.
