Some logging middlewares like https://github.com/grpc-ecosystem/go-grpc-middleware/blob/main/interceptors/logging/logging.go like to use dots to namespace field keys. This is not an issue using the console or JSON output formats, but sending those messages to the journald writer triggers errors on the dot character.

Do you consider the journald writer could make some attempt at sanitising those keys, ie by replacing invalid characters by _ or something else, or do you feel like it is the responsibility of the zerolog user to ensure only valid keys are used?
