In the default font used by Outlook Express, displayed on my 1078x786 
screen, the only difference I can see, using a magnifying glass on 
side-by-side characters (l1 = el-onel), is that 'el' is one pixel taller 
than the 'one'.  The serifs appear the same, down to the anti-alias gray 
pixels.  (To my surprise, this makes 'lbdk' a pixel taller than uppercase 
chars!)  Now I know ;-).  But 1 isolated from l is still difficult to 
distinguish.
