Additional context

I probably should have reported this earlier but did not. I've had this issue since at least 4.1 on macOS Ventura 13.4.1.

The problem is that (for example) Latin texts, particularly ecclesiastical Latin with Gregorian chant in modern notation, depend on accented letters available with Unicode but not the basic keyboard (e.g. the glyph in question ǽ (U+01FD) as syllabic accentuation is not absolutely determined by the number of syllables particularly in words of three syllables, to say nothing of languages where there is nothing optional about the diacritic or accent mark.

A related trouble is that copying and pasting moves the cursor to the next note (syllable). This is also infelicitous, but could be ignored if Unicode entry were to be supported again.
