My first intuition would be to take all the characters in the range
[A-_] (preserving case), then to "double" each character that has an
uppercase and a lowercase variant.
So we are talking about the characters "ABCDEFGHIJKLMNOPQRSTXYZ[\]^_"
for the given range, and now we make a case-insensitive variant of
this list of characters.
Does this make sense? Is it feasible to implement?
