UnicodeIt

To use UnicodeIt in a JavaScript or TypeScript environment, install it via npm:

npm install unicodeit --save-dev

Use the replace method to convert LaTeX tags to Unicode:

var unicodeit = require('unicodeit');
console.log(unicodeit.replace('\alpha'));

You can create a macOS Quick Action (Service) to convert selected text to Unicode using a keyboard shortcut.

Setup Steps

1. Open Automator and create a new Quick Action (or Service).
2. Set the defaults at the top to: Service receives *selected text* in *any application*.
3. Check the box: output replaces selected text.
4. Add the Run Shell Script action.
5. In the dropdown, select pass in: as arguments.
6. Enter the following command (ensure your Python interpreter has unicodeit installed): /usr/local/bin/python3 -m unicodeit.cli $1

Assign a Keyboard Shortcut

1. Go to System Preferences → Keyboard → Shortcuts → Services → Text.
2. Find your new action (e.g., UnicodeItAction).
3. Assign a shortcut, such as Command+Option+Shift U.

You can use UnicodeIt in Python projects to convert LaTeX tags to Unicode characters.

To install the package, use pip:

pip install unicodeit

CLI Usage

Run the conversion directly from your terminal using the module CLI:

python -m unicodeit.cli \alpha

Programmatic Usage

Import unicodeit and use the replace function to convert strings containing LaTeX tags:

import unicodeit
print(unicodeit.replace('\alpha'))

UnicodeIt supports a wide variety of LaTeX tags. Common examples include:

\alpha α, \beta β, \infty ∞       e^+ e⁺, \mu^- μ⁻               \exists ∃, \nexists ∄
\int ∫, \sum ∑, \partial ∂        \to →, p\bar{p} pp̅             \mathcal{H} ℋ, \mathbb{R} ℝ
\slash{\partial} ∂̸                \underline{x} x̲                \phone ☎, \checkmark ✓
\dot{x} ẋ, \ddot{x} ẍ             A^6 A⁶, m_0 m₀                 \Im ℑ, \Re ℜ, \hbar ℏ
\gamma γ, \Gamma Γ                \~{O} Õ                        \perp ⊥, \parallel ∥
\sfrac{3}{5} ⅗                    \therefore ∴, \because ∵       \subset ⊂, \supset ⊃

The primary entry point for the unicodeit JavaScript/TypeScript library is the replace function. Use this function to convert LaTeX mathematical expressions into their Unicode equivalents within a string.

import { replace } from 'unicodeit';

const latexString = '$\alpha + \beta = \gamma$';
const unicodeString = replace(latexString);
// Result: 'α + β = γ'

You can use the unicodeit CLI to replace Unicode characters in strings passed as command-line arguments. The CLI accepts one or more strings and outputs the processed strings separated by spaces.

Each argument provided to the CLI is processed individually by the replace function.

# Example usage (assuming unicodeit is installed and in your PATH)
unicodeit "Hello ℌello" "Unicodeit 🚀"
