Reply from Eclipse JDT forum points to a couple of bug reports.
Both made interesting reading for me.

Cf. https://bugs.eclipse.org/bugs/show_bug.cgi?id=547817 , 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=547601
Feel free to join the discussion in either of these bugs.

So, for my own use; I think I will do more reading around
Unicode UAX#31 before I decide how to implement my names.
