ETW fields containing spaces

[lischach]

I am currently writing an ETW provider using this crate, and need to send an event, with a field that contains spaces.
I saw that the recommended way to send events, is using the trace_logging_provider macro, for example:

  #[trace_logging_provider(
            guid = "ee756ff4-11ee-4682-8e49-c833206e2d90",
            name = "MyTestProvider7"
        )]
        pub trait MyTestProvider7Events {
            fn Event1(data: i32);
        }

        let provider2 = MyTestProvider7Events::new();
       provider2.Event1(None, 1);

Is there any way, which I can have the event field (data in this example), contain spaces? So the actual ETW event that will fire, will have a field named "My data".
