I wrote a little program for other standards activities to check which Unicode characters have simple lower-/uppercase mappings across UTF-8 length boundaries (0080, 0800, 10000).
This is with Unicode 4 data.
I thought some unicode subscribers might be interested in the result.
Best regards, markus
