Bracket character in SNMP community string // IOS-XR

Hi guys,

I've just tried to configured a SNMP community string in IOS-XR 4.1.2
without success I got the follow error:

snmp-server community %test&)

RP/0/0/CPU0:ex-RR1(config)#snmp-server community %test&)
                                                          ^
% Invalid input detected at '^' marker.

RP/0/0/CPU0:ex-RR1(config)#snmp-server community %test&)fasar
                                                          ^
% Invalid input detected at '^' marker.
RP/0/0/CPU0:ex-SISRR1(config)#

This community string was working well in regular IOS. Maybe that is a
bug, anyway have you experimented before that error? or maybe I'm wrong.

Rgds.
