I've made a change to LaTeX editing on mathstodon.xyz: unicode equivalents outside maths delimeters are no longer automatically inserted. Instead, when you select a LaTeX autocompletion, if it can be rendered using just unicode, that's inserted instead of the LaTeX code.

For example:

𝑓 : 𝑋→𝑌 = sin(θ²)

was produced by writing

\( f: X \to Y = \sin(\theta^2)

and pressing enter.
