I know. But there is no mention (that I have found) of "invalid base characters" or any recommendation for using dotted circles especially for Indic scripts. > I add that this is a good way of displaying a combining mark that has no > base character, i.e. one occurring at the begin of a line or paragraph. No, those should be displayed *as if* preceded by a SPACE (TUS 3.0 page 121). /Kent K
