Garamond is atop showing off tilde a’s with the same input at bottom. The input given is but the result uniquely differs; no other font does this.
I discovered this when I tried to change the default font of my games chat room to Garamond and couldn’t spell aardvark. It persists in all types of text.
To reproduce, just type AA
into a text label using the garamond font.
I was recommended to file a report in my original post Changing default chat font to Garamond causes a tilde to be added to certain letters in succession
