We've been sent a list of special characters to make up for a book In Sun's Likeness and Power: Cheyenne Accounts of Shield and Tipi Heraldry.
Most I can figure out, like
"capital A with right-opened half ring above"
But then we hit
"a with acute and slanted half 'c' above"
Which is clearly different that the half ring.
Anybody know what a "slanted half c" is in the Cheyenne language, or anything else, for that matter? If not a character in Unicode, then in anything? It may be *signage* as a part of the heraldry rather than a linguistic use, and I'll get up with the authors if needed, but it is going to be one of those things that will have to be done quickly (& isn't everything these days?).
