After having a look through the site on a couple different smartphones (both iPhone and Android), wherever there is an ‘fi’ or a ‘fl’, they get replaced with a small square symbol. It seems to only be when an ‘f’ is with an ‘i’ or an ‘l’ (fashion, for example, is fine). How can I fix this? To see what I mean, check this page on a smartphone and scroll to second paragraph. You can see an example with the word ‘confidence.’
I can try changing the font, but I’d like for that to be a last resort.
