Hi Mirjana,  Attached is the promised set of test cases.  I mostly focused on a) Excluded glyphs -- to test that they actually get rejectedb) glyphs which are in MSR, but not in our repertoire.  (I confess that I ran out of gas after the Latin Extensions A and B.)  Again, to test that they actually get rejected.  In the course of this, I came across the Serer language (ISO 639-3 srr).  It isn't in our list of languages included, but it is EGIDS 5 and has roughly 1.2 million native speakers so it would appear to fit our criteria.  Also the Kpelle language (ISO 639-3 kpe), which is also EGIDS 5 and has about 1.4 million native speakers.  Adding Serer would entail adding 3 code points for Serer to the repertoire: U 0188  Small Letter C with Hook  ƈ  U 01A5  Small Letter P with Hook  ƥ   U 01AD  Small Letter T with Hook  ƭ  For Kpelle we would also need to add: U 0260  Small Letter G with Hook  ɠ  We might pick up a couple of Variants as well.  For example, a P with Hook (ƥ) resembles a Thorn (þ) far more than a P alone does.  Alternatively, of course, we could simply ignore them.  And hope we can skate thru Public Comment without anybody noticing -- which, given the small number of ICANN members from West Africa, seems moderately likely.  Bill
