D'ni LM maps the D'ni characters to special characters, whilst the current D'ni font maps them to upper and lower case letters. Here's an example of the two side-by-side:
!Sora .reKUan treKleft
!šora .rekúan trekleft
Ok, maybe not the best example in the world. Here's the full alphabet.
'.vbtsSjgykKaIfpiEeArmTdDhoOcwuUxlåzn
'.vbtsšjgyxkaáfpiíeérmþðhoóçwuúclæzn
One looks ugly, and one is hard to type. Well, even the current D'ni font has a hard-to-type character, å, unless you are very familiar with how to type them. I have become used the the second font, but I do reccomend the first font for the beginner.
