To many people, those two look the same. Example, I'm typing l and 1—which was which? In this blog window what I typed looks identical.
In actuality, the first character I typed was the lower case L (l) and the second one I typed was the number 1— side by side, lower case L and number 1—l1l1l1.
It all depends on the font. In the compose font on my blog interface, they both look the same, but when you read this, the font will show a difference between the two with the lower case L being a straight line and the number 1 having a little slanted line at the top.
On Google apps, the lower case L has straight line at the top and the number 1 has a slanted line at top.
