I installed the Crisa Regular font [1] (font name is “Crisa”) and tried to type some zbalermorna [2] (an abugida) into Emacs.
However, the positions of the vowels are not correct, as shown in the attached screenshot obtained in emacs -Q.
The vowels should be right above the constants.
The correct rendering can be seen at this web page [3] (using a decent modern Web browser).
I can confirm other applications using the system GUI toolkit works, e.g. TextEdit.app.
