More symbols are supported by TeX math packages, see e.g. Will Robertson, Symbols defined by unicode-math. https://tug.ctan.org/fonts/xcharter-math/unimath-xcharter.pdf#page=47 ↩
The quadruple arrows U+2B45 and U+2B46 are supported by TeX math packages, per Will Robertson, Symbols defined by unicode-math. https://tug.ctan.org/fonts/xcharter-math/unimath-xcharter.pdf#page=75 ↩
As per Unicode 16.0.0, the ASCII hyphen-minus is not a mathematical symbol. To express the minus sign in math, U+2212 − MINUS SIGN is used instead. https://www.unicode.org/Public/16.0.0/ucd/DerivedCoreProperties.txt ↩
As per Unicode 16.0.0, the degree sign is not a mathematical symbol, since it is a measurement unit symbol rather than a math symbol. Consistently, TeX packages support many non-math symbols. But this article is designed to cover only Unicode characters with a derived property of "Math". https://www.unicode.org/Public/16.0.0/ucd/DerivedCoreProperties.txt ↩
