We are migrating an ETL process from DataStage to scala using your libraries. The file has fields that are handled as "Raw" and converted with the iconv function to hexadecimal. But we are losing bits and we cannot solve it. They are fields that have packaged bits inside.

We read them as follows
.withColumn("field", hex(col("field")))
