🎯 Subject of the issue

Experienced behavior:
The CaskaydiaCove Font linked in the release 2.1.0 doesn't contain German umlauts.

Expected behavior:
The CaskaydiaCove Font should contain German umlauts as the original Cascadia Code Font does contain them.
Furthermore, running fontforge -script font-patcher src/unpatched-fonts/CascadiaCode/Regular/CascadiaCode-Regular.otf -c --mono --out . generates a font which contains German umlauts as well.

Example symbols:
German Umlauts are affected.
However, I'm not sure whether there are more accent characters which are affected.

• German umlauts

Update: All accent characters are missing
