Getting NULL character in string when using SerializeToString

[Saurabh Grade]

Hi,

Using SerializeToString to serialize a protobuf object and getting NULL character in serialized string.

What could be the reason of this?

How can we avoid NULL characters in serialized string?

Please let me know if more details are needed.

Thanks in advance.

Thanks and Regards,

Saurabh Grade

There is no practical way to avoid having zero bytes in the serialized message. For example, zero-valued integer fields will show up as zero bytes in the serialized message. If you need the serialized form to contain only printable characters, you could try base64-encoding it as an additional step.
