> Ligatures are fading from use in contemporary printing, probably due to the rise of computers.
If somebody doesn’t use the fi ligature when using Serif fonts, he is an idiot, because of the crappy dot clash. Copy “fi fi” to your favorite WYSIWYG text editor program (Word{,Pad}/{Libre,Open}Office) with Times New Roman at a small size. (too big fonts/zoom may break this, and don’t forget that you can zoom paper in much better than an LCD display).
{La,}TeX, the most superior typesetting system in existence, does ligatures of certain words automatically.
