---------------------------------------

[~andrew_duffy] do you have a link to the corresponding avro / spark code handy? That would make fixing this much easier.

> FromStringBinary is the Binary-type for UTF-8 strings, but uses the old comparison method of byte-by-byte instead of being UTF-8 aware like Avro and core Spark. This should be fixed so that the BinaryStatistics generated for String columns that contain non-ASCII text will actually be useful.
