Relatedly, I appreciate that most Unicode math symbols are in the built-in Windows emoji IME opened with Win+. or Win+; whichever feels more comfortable. Unicode math stuff is under the Omega (Ω) tab. The biggest shortcoming is that emoji themselves have type-to-search, but math/international symbols don't and you either get to mouse through it or arrow/tab/enter through it. But the nice advantage is that it has been built-in for several Windows versions now and you can count on it to work nearly everywhere.
