 I just tried it on one of my MIBs and it worked:

# snmpset -v1 -cprivate localhost 1.3.6.1.4.1.1978.21.1.7.7.0 x
414243444546474849
SNMPv2-SMI::enterprises.1978.21.1.7.7.0 = STRING: "ABCDEFGHI"

But:
a) my definitions does not use a TEXTUAL-CONVENTION
b) nor do I have a STRING size limit of 8.
c) I didn't specify the variable by name (thereby avoiding snmpset's
   reading/interpreting the MIB file).
