I am ingesting SQL Server ErrorLog files using Filebeat with the mssql module directly to Elastic search output but I am getting characters like this u00000u00002u00004u0000-u00000u00004u0000-u00002u00005u0000 u00002u00002u0000:u00001u00000u0000:u00000u00003u0000.u00002u00005u0000′ could not be parsed at index 0 in the message field.
