I don't know who stole my €-char. It is supposed to be on AltGr-e, but my keyboard doesn't do it. There is a discussion about the same problem. On the thread on French keyboard layout the problem is not solved.
On my Finnish keyboard layout even Windows On-Screen Keyboard -application displays AltGr-e as the soure, but to my great amazement adds a 2nd source for the €-char, AltGr-5. WTF?! It works! See pic below:
Hope this helps somebody. Unfortunately I could not determine who stole it/where my original euro-key went.
