Generate Bold, Italic & Script Unicode Text Convert text to Unicode styled variants — bold, italic, script, fraktur, and more.

The tool works by utilizing JavaScript's `useState` and `useCallback` hooks from the React library to manage state and memoize functions. It defines a constant object `STYLES` that stores mappings of standard characters to their corresponding Unicode characters in the Mathematical Alphanumeric Symbols block. Each style, such as bold or italic, has its own mapping defined using `Object.fromEntries` and `Array.from`, which generate key-value pairs for letters and digits based on their ASCII values and Unicode code points.

When a user selects a style from the dropdown menu, the `onProcess` function is triggered, which uses the selected style's mapping to replace each character in the input string with its corresponding Unicode character. The function iterates over the input string using `[...input].map`, looks up each character in the mapping object, and returns the replaced character or the original character if no replacement is found. The resulting string of Unicode characters is then joined back together using `join('')` and displayed as output.

The React library's Virtual DOM and event handling mechanisms enable efficient updates to the UI when the user interacts with the tool, such as selecting a new style or typing in the input field. Meanwhile, JavaScript's built-in support for Unicode strings and characters enables accurate representation and manipulation of the Mathematical Alphanumeric Symbols block characters. The `TextToolLayout` component provides a structured format for presenting the input field, output label, and style selector, making it easier to manage the tool's layout and behavior.

The use of Unicode code points, such as U+1D400 and U+1D41A, allows for precise control over character mapping and ensures cross-platform compatibility. The tool's implementation also relies on standard JavaScript data structures like objects and arrays to store and manipulate the character mappings, making it efficient and easy to maintain. By leveraging these technologies and techniques, the tool provides a robust and user-friendly way to generate Unicode text in various styles.
