It seems something strange is going on with the glyph Å in EB Garamond. Consider this example:
\documentclass{memoir}
\usepackage{ebgaramond}
\begin{document}
Test Å Ä Ö
\end{document}
I compiled this as:
% latexmk -pdf test.tex
on my Mac. The ring is supposed to be centered above the A but it is not. Can this be fixed somehow?
If I instead do:
% latexmk -lualatex test.tex
or:
% latexmk -xelatex test.tex
it looks much better.
If I try on https://googlefonts.github.io/ebgaramond-specimen/ I get this effect:

Which also makes me somewhat hopeful. Why will not LaTeX produce the same output and what can be done about it?

pdflatexyou should use\usepackage[T1]{fontenc}(underxelatexorlualatexyou should not). – daleif Dec 08 '23 at 14:44fontspecpackage. There are some old fonts that are not designed for this, but there are many new fonts that are better, and you can also use commercial fonts if you have the license. Some fonts (including EBGaramond) have the new OpenType. If you have the package, it is already in your system. – rallg Dec 08 '23 at 19:57
