This proposed use of CGJ would *mostly* affect font rendering implementations that would have the job of making it look right. But if you think that font developers are going to implement fonts that can have diacritics spanning an arbitrary length of base characters, you've got it wrong. Not only would it be a pain to implement, but typographically it doesn't make much sense to have to have dot below, a comma above or even a tilde or circumflex spread out over a span of 15 characters, or even 5 characters. IMO, the number of diacritics it typographically makes any sense is very few, and generally it only makes sense to have them span a very short span of base characters. An overline and underline are the only things that typographically could reasonably span long sequences of base characters, and that is not needed for any writing system for linguistic expression; it is only potentially needed for technical notations, such as math, and for that there are better solutions. Rick has convinced me: in the absense of any indication of a real need for some productive mechanism, let's keep this one simple: somebody please propose two more double diacritics. - Peter --------------------------------------------------------------------------- Peter Constable Non-Roman Script Initiative, SIL International 7500 W.
