an AZERTY keyboard needs ALTGR+2 to type a "@" sign, it needs ALTGR+E to type a "€" sign etc.
this does not work in Kiosk mode, which is a little bit a pain if you generate a kiosk app to collect e-mail addresses. I have a general feeling that the "ALTGR" button no longer works in "Full screen" mode. Apparently other apps like Remote Desktop etc causes the same problem.
FileMaker Pro Advanced 17.0.2
OS: Windows 10
People could type a "@" sign with Windows 10 in Kiosk mode and an AZERTY keyboard
Steps to reproduce
Create a Kiosk app with a field in it
Enable kiosk mode
login with a Windows 10 machine and an AZERTY keyboard layout
try to encode a "@" sign using ALTGR+2
