In many fonts I come across, I see that the glyph uppercase i - I is same as lowercase l.
Why is it so? Why don't font designers add a differentiating factor between the two glyphs?
This specially creates a problem with the word 'Ill'. Whether to read it roman 3 or short for 'I will'.
I am asking this because I am making a font, so I want to know if I should stick to this standard design, or use different glyphs for the two... Also, see my last question on fonts as well.
P.S. I don't know if this should goto SuperUser, but I can't post questions there.
