All, let me try to explain the problem of excluding certain code points from different sets when doing the analysis. Let’s assume two scenarios for the hypothetical analysis: Scenario 1: Set 1 = {A, B} Set 2 = {A, C} For Set 1, it was concluded A is a variant of B. In Set 2, it was concluded A is not a variant of C. Then, the only resulting variant set is A --> B (symmetry implied) Scenario 2: Set 1 = {A, B} Set 3 = {A, B, C} For Set 1, A is deemed variant of B In Set 3, A is deemed variant of B, B deemed a variant of C, but A not a variant of C. The resulting variant sets are A --> B, B--> C; and due to transitivity A-->C is also a variant pair. My point was that by excluding a code point from the analysis can result in different result as to the variant sets identified. Hope this helps clarify. Dennis
