Hi, I've been using protobuf 3.5.1 in c++ and am using a message type with the following map type: `map<string, MyObject> txns = 1`
It is my understanding that `string` and `bytes` are the same in proto c++; for maps however one can only use `string` as keys. I'm using the key field to send around transaction digests which are byte strings consisting of cryptographic hashes. As far as I can tell, it makes no difference whether I use strings/bytes (the decoding works), yet I keep getting the error: `String field 'pequinstore.proto.MergedSnapshot.MergedTxnsEntry.key' contains invalid UTF-8 data when serializing a protocol buffer. Use the 'bytes' type if you intend to send raw bytes.` I understand the error is complaining about my digests possibly not being UTF-8, but I'm unsure if I actually need to be concerned about it; I have not noticed any problems with parsing. Is there a way to suppress this error? Or, if this is a serious error that could lead to non-deterministic behavior, do you have a suggested workaround? There is a lot of existing code that uses the map structure akin to an STL map, so I'd like to avoid re-factoring the protobuf into a repeated field if possible.
