* Description

This utility lets you input math symbols by TeX names
with the following commands.

- M-x toggle-input-method + math-symbols-tex
- M-x math-symbols-from-tex-region
- M-x math-symbols-insert
- M-x math-symbols-ivy

Also, you can convert character to TeX names by the following command.
- M-x math-symbols-to-tex-region
- 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.

- M-x toggle-input-method + math-symbols-italic (or script, etc.)
- M-x math-symbols-italic-region
- (math-symbols-italic-string "target string")


* 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)
: "black" → "𝒷ℓ𝒶𝒸𝓀" (M-x math-symbols-script-region)
: "Quo Vadis" → "ℚ𝕦𝕠 𝕍𝕒𝕕𝕚𝕤" (M-x math-symbols-double-struck-region)
: "3+(2-1)=4" → "³⁺⁽²-¹⁾⁼⁴" (M-x math-symbols-superscript-region)

* Required Font
