The bidi package implements the Unicode Bidirectional Algorithm (UBA) to correctly render text with mixed right-to-left and left-to-right scripts, such as Arabic, Hebrew, and English. It converts logical character sequences into their proper visual order, ensuring accurate display in multilingual applications. This is essential for localization and internationalization, particularly in regions where RTL languages are used. The package supports all major platforms, including mobile, web, and desktop, making it a reliable choice for globalized apps.
