Hello,



It seems there's a discrepancy between the tests and the spec for grapheme clusters. In



http://www.unicode.org/Public/9.0.0/ucd/auxiliary/GraphemeBreakTest.txt



we have:



÷ 261D × 0308 × 1F3FB ÷

# ÷ [0.2] WHITE UP POINTING INDEX (E_Base) # × [9.0] COMBINING DIAERESIS (Extend) # × [10.0] EMOJI MODIFIER FITZPATRICK TYPE-1-2 (E_Modifier) ÷ [0.3]



which is



http://www.unicode.org/Public/9.0.0/ucd/auxiliary/GraphemeBreakTest.html#r10.0



but the spec doesn't talk about interleaved Extend*:



http://www.unicode.org/reports/tr29/proposed.html#GB10



It seems following the spec this would be:



÷ 261D × 0308 ÷ 1F3FB ÷



which one is right ?



Best,



Daniel
