If a can have U+0061 and have a composite that is U+00e2...U+... If e can have U+0065 and have a composite that is U+00ea...U+...
Then why is e with accented grave or acute and dot below cannot be assigned a single unicode value instead of the combinational values 1EB9 0301 and etc.... Since UNICODE is gradually becoming a defacto, I still think it will not be a bad idea to have such composite values. Dele Olawole
