The changed l (letter) looks a lot like 1 (number). Perhaps someone using the font can confirm or deny this?
I think the original artist drew the L weirdly to make it extremely clear that it’s not a one, but if you draw a gothic one, the difference is obvious even with a simpler L.
Even if you're not on a Mac it shouldn't be difficult to find one or two.
On my iMac I find that Menlo has a very subtle fuzziness to its characters. Monaco (10pt) remains my setting for now. Despite being not very pretty, it is very crisp and the letters (aside from l and 1) are very distinct and legible.
