I am writing in Croatian and since the font used in the editor does not have the letters specific to our language (čćšđž), a substitute font for this letters is used, making the text look a bit ugly. Can you use the Latin Extended-A version of the font that includes all the characters used by most languages that write in Latin script? Novlr currently uses the Merriweather font (sans) and as far as I can see, it has Latin Extended-A (Google fonts).
