I am trying to display them in a custom NSView that displays math. Of course not all, at the same time, but single characters when needed in a math formula drawing.

For unicode characters in the 16 bits range I use the following code:

  NSGlyph glyph = [font _defaultGlyphForChar:ch];

  NSBezierPath* path = [[NSBezierPath alloc] init];

  [path moveToPoint:NSMakePoint(rect.origin.x,rect.origin.y)];

  [path appendBezierPathWithGlyph:glyph inFont:font];


This works fine for characters in the 16 bits range. Outside this range, I am in trouble since input to _defaultGlyphForChar is 16 bit.

If all you want to do is to display a character in a given font, the string drawing APIs will work just fine for that. If you really need to have a bezier path, don't use the code you show here; we have a sample showing how to get a bezier path from text--look at bezierWithFont: in http://developer.apple.com/mac/library/samplecode/SpeedometerView/listing9.html .
