Indeed, it immediately made me think of Welsh, where native-speakers' use of their vigesimal system has been hammered by the use of Arabic numerals. (In England, resistance to this 'heathen notation' collapsed long ago.) Before anyone points it out, I do know that Welsh _pymtheg_ '15' and possibly even _ugain_ '20' ultimately derive from a (superseded) decimal system. However, Welsh goes decimal at 100, so this vigesimal notation would not match the language at all for higher numbers. > I don't think combining diacritics makes sense in this case.

No. One must be able to distinguish <ONE, FIVE> (= '25') and <FIVE, ONE> (= '101') from the notation for '6'. Or are you suggesting that rendering of ZWJ should be *essential* for the semantics, not just for acceptability? The (undemonstrated) use of the notation denoting hands for which I suggested a combining diacritic could be handled by ligatures specified by ZWJ, but there could be a lot of them. Look at the ugly mess in New Tai Lue caused by not anticipating the need for medial 'v' because the UTC knew too little about Tai Lue (or even, more surprisingly, Northern Thai). Richard.
