When use AvroUtf8InputFormat, how to remove unknown symbols(BytePrefix)

Hi All,
My folder has avro files with multiple different avro schemas.
So I use AvroUtf8InputFormat to receive data for mapper()
But I got several unknown symbols, which results to be Utf8 version BytePrefix.
Anyone has ideas on how to filter these BytePrefix?
Thanks a lot,
Fan
