Quotation mark bothers me always, I have once reported it, I will again report it, you should do the same. to
seanyword@gmail.com - he usually fixes things and listens to suggestions.
He is asian, maybe he is just not aware that such characters as "' etc have to be bound to the word.
Another bigger issue is, loading themes does not consistently load fonts, some attributes and italic variants. It does after a restart of moon+.
In otf fonts, it does not load the respective italic font at all.
"The respective italic" imo is:
Bookerly-Regular.ttf
-> Bookerly-Italic.ttf"
It seems to follow such file naming conventions.
