Problem with diacritic «Combining Vertical Line Above» (U+030D)

[theblursed]

Dear georgd,

Firstly, let me thank you for the time and patience you spent for this beautiful project. I really enjoy your EB Garamond and I think you've done a great service to typography-loving people all over the world.

I wanted to tell you about a problem with combining character 030D (Combining Vertical Line Above). I use a Mac. I re-downloaded EB Garamond from Google Fonts today, to see whether the problem had been solved with some update, but it seems it's still there.

Very simply, this diacritic seems to display in the wrong positions, but this does not happen in every application. It renders correctly in FontBook and TextEdit:

While it doesn't in Word and LibreOffice:

I need these specific characters for my work in linguistics (to mark the stress in IPA directly on the vowel, in a phonemic way—it's commonly written before the stressed syllable, but that is phonetic and not phonemic for many languages, so it's not properly correct; e.g. for Italian I need to write «bello /bɛ̍llo/» instead of the common, but imprecise, «bello /ˈbɛllo/»).

Thank you in advance for anything, and keep up the good work.

PS. I forgot: it would be useful if this was addressed also for capital letters; e.g. «/V̍/» to denote a generic (stressed) vowel.
