"I would love to have a separate Unicode for negative" did make it sound like a personal wish. Other people would have loved to have separate Unicode characters for . as an abbreviation marker, a sentence-ending punctuation mark, and a decimal point.
Do you have any examples of how the TI calculators represent the two discrete symbols when interchanging data with a computer, using TI-GRAPH LINK? Does this interface exchange plain-text data, or is it in a proprietary binary format? Can the two characters leak into the outside world in any other way? Remember the bit about interoperability: with what external systems would this character interoperate?
Otherwise, the solution of U+207B SUPERSCRIPT MINUS seems to fill the need.
