No of course: the only sequence I know is a dotless ij digraph with
a centered accute accent. I just wonder if this public review makes
things clear that the presence of an accute accent is supposed to
remove both dots. For now I have seen some fonts keeping
the two dots, when centering an additional accute accent.
The text of this update should specify that for this pair, the
intended option is to remove both soft dots, if there are other
diacritics.
But if one wants to restore the preious visual behavior, even if it's
incorrect for languages using this digraph as a letter, what would be
the behavior of using the following sequence:
<ij, combining dot above, combining accute>
(i.e. should this display 1 or 2 dots?)
Should the previous incorrect rendering be approximated with:
<ij, combining diaeresis, combining accute>
or
<ij, combining dot above, combining dot above, combining accute>
???
