MessageBox Title with special characters

Hi.

I have noticed that the MessageBox, in our case, won’t show special characters in the Title, even if we encode it and set the MessageBox to show HTML. The text seems to work just fine. I have attached a picture with the word “Segurança” in the Title and in the Text as an example.

Are there any settings we need to take care of to be able to make the Titles show properly?

Thanks.

Ivan
