all: support enforce_utf8 override In 2014, when proto3 was being developed, there were a number of early adopters of the new syntax. Before the finalization of proto3 when it was released in open-source in July 2016, a decision was made to strictly validate strings in proto3. However, some of the early adopters were already using invalid UTF-8 with string fields. The google.protobuf.FieldOptions.enforce_utf8 option only exists to support those grandfathered users where they can opt-out of the validation logic. Practical use of that option in open source is impossible even if a user specifies the proto1_legacy build tag since it requires a hacked variant of descriptor.proto that is not externally available. This CL supports enforce_utf8 by modifiyng internal/filedesc to expose the flag if it detects it in the raw descriptor. We add an strs.EnforceUTF8 function as a centralized place to determine whether to perform validation. Validation opt-out is supported only in builds with legacy support. We implement support for validating UTF-8 in all proto3 string fields, even if they are backed by a Go []byte.

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.
This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.

We appreciate community contributions. See CONTRIBUTING.md.
Issues regarding the new API can be filed at github.com/golang/protobuf. Please use a APIv2: prefix in the title to make it clear that the issue is regarding the new API work.
