What is encoding of string? about grpc-go

[iamqizhao]

If you change

fmt.Println(person)

to

fmt.Println(person.Name)

it works fine. This means fmt.Println does not work well with proto message. gRPC is just fine. I am going to to talk to goprotobuf team to get help.

Are you sure that's not your terminal setup, @mattn? The protobuf package treats strings as opaque byte sequences. I don't think this has anything to do with fmt.Println or proto messages.

Hi David,

Simply on my desktop, I got

person := &pb.Person{
Name: "ほげ",
Age: int32(1),
}
fmt.Println(person)

output:
name:"\343\201\273\343\201\222" age:1

fmt.Println(person.Name)

output:
ほげ

fmt.Println(person) is rendering the protobuf message in the standardised text format, which specifies using octal escapes for non-ASCII (see https://github.com/golang/protobuf/blob/master/proto/text.go#L476). This is working as intended.

Ah, right. protobuf's textWriter seems to avoid to print non-ASCII as @dsymonds says. Should be used unicode.IsPrint instead?

The protobuf package matches the equivalent C++ code already.

fair enoguh.
