No, as the octet string has size constraints but still the hf field constructed for an OCTET STRING
Should be FT_BYTES as its Binary data, if a implementation chooses to put a string in that field you
Can override that by defining a .#ATTRIB (I think) but be aware that some other manufacturer/protocol implementer my put binary data in there and then the dissection would be wrong. Unless it's specified that even though the 
Asn1 spec is OCTET STRING a utf8 string should be put in that field.
