How do I make the infinity? Actually where do I get all those symbols?
(Sorry, I couldn't resist)
If you made a keyboard that had every character in every language spoken in the EU, you could even file to make it a standard with whatever earnest standards body is in charge of such things. No linguistic minority should have to use control keys! It would be like giving peanut butter to a dog.
But smart people don't endeavor to regulate minutia.
I think you just implied that all politicians are dumb. I agree.

As I understand only UTF-8 is supported, so forget characters for UTF-16 and UTF-32 (but you rarely need these anyway)
to answer my own question.
