I have recently had an issue with the Armenian alphabet not properly displaying on pages that do not use the default browser font. However, I have no idea what is causing this issue. Pages where the default font is used, such as Wikipedia, display the characters fine. Pages that have a set font, such as Google, display empty squares.
It should be noted that I have set all Armenian text to display in "Times LatArm," a font that is specifically for the Armenian alphabet.
