All this is new to me so I might have misunderstood it. However it
looks to me like the IDN (which I have supposed means IDentifier Name,
but maybe that is wrong) chars are selected so that the characters
choosen are not easily mistaken for other chars.

And I suppose that as many characters as possible has been included in IDN.

If my assumptions are right, would then the non-IDN chars not be the
ones to mark?

Yes, I thought of that (if someone can explain why and when it may be useful).

I thought they were choosen to more safely create URLs, programming
symbols etc. Is not that the purpose?
