It is good that, unlike some fonts, in Noto I (uppercase i) and l (lowercase L) are distinct, however, a font does not exist in isolation and it is still confusing because the average person views many different fonts in one day and does not necessarily know the details of the font he/she is viewing at the present time and when he sees an l in Noto he does not necessarily know that it is a lowercase L. The l (lowercase L) can also get confused with vertical bars | or | as well as numerous other unicode characters. Think of the $billions wasted in global human effort due to all this confusion due to pathetic form-over-function font design that dominates. If you want to create the ultimate clear and functional font then please also add a small tail to the l (lowercase L).
