      Description

      import QtQuick 2.5
      
      Text {
          textFormat: Text.PlainText
          text: "�"
          font.family: "Noto Color Emoji"
          style: Text.Raised // deleting this "solves" the issue
      }
      

       

      (Jira renders that wrong, but the text is a smiley face UTF-8 emoji)
