I hate to start new threads for a single question.
Now, for the first question:
I've been working on a couple of 8x8 fonts lately with an attempt to bulk up some of the RHDN resources. I'd like to know what characters aside from the 26 capital and lowercase letters, 10 numerical digits, and basic punctuation (, ' open and closed quotations ? / - ! &) do you find most helpful in a font? I was thinking some double letter tiles for narrow lowercase letters such as ll, il, and li, maybe...
