LaTeX to UTF-8 is a bodge to write simple UTF-8 math using LaTeX. Use the snippet tab for small math expressions and the text tab for text containing math in $...$ or $$...$$.

Mangled Latex	UTF-8 approximation
\nabla\f(\x) = 2\x	∇𝑓(𝑥) = 2𝑥
\v = \partial\x/\partial\t	𝑣 = 𝜕𝑥/𝜕𝑡
\mathbb{E}[(\x-\mu)^2] = \sigma^2	𝔼[(𝑥−𝜇)²] = 𝜎²
lim {x \rightarrow \infty} 1/x = 0	lim {x → ∞} 1/x = 0
\Delta_t \leq (1 - \kappa)^t\Delta_0	𝛥ₜ ≤ (1 − 𝜅)ᵗ𝛥₀
\Phi = \int \mathbf{E} \cdot d\mathbf{A}	𝛷 = ∫ 𝐄 ⋅ d𝐀
\partial^2\u/\partial\x^2 + \partial^2\u/\partial\y^2 = 0	𝜕²𝑢/𝜕𝑥² + 𝜕²𝑢/𝜕𝑦² = 0
\mathcal{N}(\x; \mu, \sigma^2) = exp(-(\x - \mu)^2/\sigma^2)/\sqrt\overline2\overline\pi\sigma	𝒩(𝑥; 𝜇, 𝜎²) = exp(−(𝑥 − 𝜇)²/𝜎²)/√̅2̅𝜋𝜎

This is a quick and dirty replacement of known commands to matching UTF-8 symbols. Commands that "do something" rather than produce a symbol, like \frac{}{} or \begin{matrix}...\end{matrix}, do not work.

Props to Günter Milde for the Unicode ⟷ LaTeX mapping.
