They are older than Unicode. It could have been possible in the beginning of Unicode to define U+0649 to have initial and medial glyphs with dots, i.e. to be the character that now is U+06CC. Please note that fonts in MacArabic, MacFarsi, ISO-8859-6 and fonts from Windows XP have only isolated and final glyphs for U+0649. This is of course an Arabic letter. > If U+0649 is in these character sets, to say that it's really > a Uighur character In my view, U+0649 is made an Uighur letter by defining inital and medial glyphs to have no dots.
