No, very straightforward!
Thanks for the explanation.

One thing that occurs to me in accessing these plane 1 maths  
characters is that on first impressions, it seems \XeTeXcharglyph  
can't be used to see if they exist...I don't know if that's something  
that we want to investigate, though, because it would be costly in  
terms of performance. Any thoughts?
