I'm using the Mac version of Affinity Publisher 2.04. I've seen similar questions in
and elsewhere, so I suspect the developers are aware of this, but I'd like to add my voice to a less specific and more generic topic, the input of diacritical marks in general. I have a need for some specific unicode combinations, the combining inverted breve below, as in ι̯ (Greek iota with the inverted breve below U+032F, standing for a non-syllabic iota or semi-consonantal glide) and combing ring below, as in λ̥ (Greek lambda with a combining ring U+0325 below, standing for a syllabic lambda acting as a semivowel). Both diacritical marks are supported by my font, Gentium, which is designed for Greek and diacritical marks. I can produce these as composite unicode characters that register as a single glyph in other Mac programs like Pages, but they are treated as two characters in Affinity Publisher, whether I produce them manually with the Mac "Show Emoji & Symbols" menu in Publisher or paste them in from Pages or another application. The λ̥ typographically appears correct in Publisher, with the ring centered under the letter, and I'm okay with that, but the ι̯ appears as two separate characters, with the combining diacritic placed first, under empty space, and the iota second, over empty space.
Is there a method to input these characters in such a way that they appear in Publisher as combined unicode characters, or is the unicode implementation in Publisher bugged? Having looked at other reports on the forum, I haven't found a solution that lets me create the iota with inverted breve below in a fashion that appears to be a single character.
