Hello,

I’m making a font and I’m trying too add alternate characters using for example the following code.

feature zero {
sub zero by zeroalt;
} zero;

So I’ making extra characters by adding an -alt suffix. For example “zero” becomes zeroalt.
So far so good. But my question is the following: What do I do with the Unicode of these new characters?
The Unicode for “zero” is “0030” but I can’t put my alternate “zero” at “0031” because that’s taken by “one”.
What are some possible unicode solutions for “zeroalt”? And is a uncode necessary for these alternates?

thx
