Can you use keyboard command characters?

To log into a particular website forum I belong to, I need to use the character "ß" which is created by holding down the alt key and typing 225.

I know there is no Alt key on the keypad so is there a way around this?

 

Yeah, that's what I ended up doing after all.

As often as the copy option pops up by accident when I'm scrolling through the news, it was a real pain to get it work when I tried to copy my name from the website. I don't know if the site has some particular coding but it would only copy the URL address of that page. But anyway I finally got it after about a dozen attempts.
