SNMP Trap - Encoding Issue


I am using snmp trap input plugin to receive snmp traps.
I am receiving SNMP v1 traps but on some fields there seems to be hex binary encoding.
Here's a sample of my messages:

#<SNMP::VarBind:0x329c49fd @name=[], @value="\a\xE7\v\x0E\x05\b\v\x00">, #<SNMP

I am wondering what I can do to fix this perhaps at the input level or filter level?
