It just changes the direction behavior, it does not replace characters, except in the preference mode using "national digits". Still changing Euro-Arabic digits to some Arabic digit required more knowledge about the language. And the BiDi algorithm does not track languages.
So you cannot choose with the BiDi algortithm **alone** how to substitute Euro-Arabic digits to one of the two sets of Indo-Arabic digits (Western or Eastern; the eastern set being called "extended" in UCD but being the natural system of digits for Persan, Pashto, Urdu, and used by many shiite muslems, the former western set being used also in Arabic by most sunnite muslems)... 2014-07-07 16:13 GMT+02:00 William Blackwood <[email protected]>: > Doug, from Unicode Standard Annex #9 Unicode Bidirectional Algorithm: > > > 3.3.4 > > W2.
