Q: About Firebase console errors When I try to create an Audience in the Firebase console, the following message appears and the creation is not executed.
One or more of your fields contain invalid characters.
I could not find any information about this message in the official documentation.
Do you have any idea why the message is displayed?

A: I was able to verify this in my environment.
It seems to occur at least when Event contains Japanese characters.
I can set Japanese in the event, but it seems that cannot create Audience that contains Japanese.
