> 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.
