The lack of support for special characters is inacceptably poor security. There is no way I wil cgange my WiFi PWd to remove special characters -- which violates recommended security practices. This demonstrates a complete lack of care for security with IoT, and I would NEVER use or recommned Iris for anyone based on this. This is security failure of first order. The developers are incompetent or just don't take security seriously. You really need to rethink your development process that would EVER alow this out the door.
