Only powers from 2 to 9 are shown in superscript

1. Run qalc
2. Execute 2^9. qalc displays 2⁹ = 512, as expected.
3. Execute 2^10. qalc displays 2^10 = 1024, while perhaps it should display 2¹⁰ = 1024
4. Execute 2^-9. qalc displays 2^−9 = 1/512 = 0.001953125, while perhaps it should display 2⁻⁹ = 1/512 = 0.001953125.

Multiple consecutive Unicode exponents generally looks bad with monospaced fonts. Apart from the wide spacing, many common monospaced fonts does not include superscript minus and zero, causing vertical misalignment and inconsistent appearance. Superscript minus might be misaligned even when displayed using the same font.
