HttpRequest.Headers.TryGetValue Encoding Bug.

[pulmuone]

When the client enters Japanese or Korean characters in request.Headers.TryAddWithoutValidation and sends them to Azure Funciton, they are converted to strange characters. However, it is processed normally on the local development PC. Why does Japanese or Korean look strange only on my Azure Function server?

public static async Task Run([HttpTrigger(AuthorizationLevel.AuthLevelValue, "get", "post", Route = null)]HttpRequest req, TraceWriter log) { if(req.Headers.TryGetValue("Team", out var team) ) { Debug.WriteLine(team) // } }

Client Input Value : ラインシステム Azure Function (Azure Online Server) Debug Result : %C3%A3%C2%83%C2%A9%C3%A3%C2%82%C2%A4%C3%A3%C2%83%C2%B3%C3%A3%C2%82%C2%B7%C3%A3%C2%82%C2%B9%C3%A3%C2%83%C2%86%C3%A3%C2%83%C2%A0

@pulmuone Do you see the same behavior when trying in an aspnet core web api?
