Hello,

I'm hoping someone can help me out a bit here..

I've developed a C++ GRPC server (Question is protobuf specific though), 
that talks with a Java client. The C++ server takes data from an older C++ 
API and converts it to protobuf and then uses GRPC to send the data.

However it appears that there may be a bug in the older API and i'm 
occasionally being sent garbage in some char*, which when they get to java 
result in an Protocol message had invalid UTF-8.

It seems slightly odd that on the C++ side the protobuf is happy to accept 
and encode invalid data, but the Java side throws an exception.

Is there anyway from the C++ side to validate the messages strings before 
they are sent. I've noticed if i convert the message to JSON the strings 
just stop at the first invalid character they reach. I looked at trying to 
find a simple UTF8 validation in C++ but not had much luck with this (Sorry 
C++ is really noy my main language)

Developing in Visual Studio 2017 with C++11 support

Thanks,
Robin
