U+01DD, the "latin small letter turned e" = ǝ is included in Libertinus (hurrah!). Unfortunately it has a slight kerning problem in the upright font, which is more pronounced in the italic, which (in conventional use in my world) is its typical usage (for semitic transliteration).
One would expect it to sit "neatly" in its space, but in fact it is shifted to the left (more obvious in italic than upright), so that there is a gap on the right. It is marked in this screenshot (which ironically tends to obscure the issue slightly!), but it is readily reproduced if you input some text, and copy/paste the glyph from above into it—then apply italics.
I have included the same text in Brill (which is better behaved here) for comparison. Not a major issue, but would be great to have this tweaked!
