I am seeing some odd behavior with the Charis-SIL font across different programs. I want to understand what is going on before reporting a bug with either the font or the offending programs. I am running MacOS 10.14.6, Safari 13.1, Pages 10.1, and GIMP 2.10.14. I installed the Charis SIL font 5.000 on June 8.
Certain characters look different depending on which program I am using. Most of the differences are trivial, but the vav, nun sofit, and yod lack any horizontal portion. I enter Hebrew characters using the Hebrew-QWERTY keyboard. In Pages, they look correct. In GIMP, they look wrong. When I opened the Pages file on my iPad (iPadOS 14.6), they also look wrong. When I export as a PDF from Pages, it looks correct both on the Mac and iPad. Here is an example of vav:
Most other characters display differently but are recognizable for what they are.
The webpage Loading... (fourth quiz question) displays 2 of the vavs incorrectly but one is correct. The same page displays vavs properly in FireFox and Chrome on my same computer.
Is there a step I missed in installing the font? Is this a known problem? Is there a workaround?
