I'm pretty new to the text engine myself, but I don't think an NSGlyph can be generated by typecasting a char. Since Monaco or Courier are monospaced, it just so happens that you get the same width as the space would be. But the glyph with number 0x20 is probably a completely different width than the glyph corresponding to a space in other languages.

Have you tried asking the glyph storage (I think that's a category that the layout manager adheres to, or maybe it was the text storage) for the correct glyph for the character ' ' ?
