Default font does not support label special characters

[gaiterjones]

Special characters in labels are showing as question marks i.e.

N?man instead of Nüman

I think this is because the default font helvetiker regular doesn't support special characters. How do I uselabelTypeFace([typeface ]) to specify a different/custom label font created with facetype.js or is there another built in font I can use, or am I doing something wrong with special characters?

So I did get it working with something like this using optimer_regular which supports special characters.

var labelfont:
    $.getJSON('https://raw.githubusercontent.com/mrdoob/three.js/dev/examples/fonts/optimer_regular.typeface.json', function(data) {
        labelfont = data;
    });
...
.labelTypeFace(labelfont)
...
