• M-x math-symbols-to-tex-unicode-region

You can also input various styled mathematical symbols by input methods, or by specifying region or string, as shown in the following examples.

Examples:

TeX to Char Conversion

"\int g(x^2)dx = \pi e^(ix)" → "∫ 𝑔(𝑥²)𝑑𝑥 = 𝜋 𝑒^(𝑖𝑥)"
(M-x math-symbols-from-tex-region)
"f(x+y)" → "𝑓(𝑥+𝑦)" (M-x math-symbols-italic-region)

Character to Math-Character Conversion

"Fraktur" → "𝔉𝔯𝔞𝔨𝔱𝔲𝔯" (M-x math-symbols-fraktur-region)
