Unicode Collation Algorithm

The Unicode Collation Algorithm (UCA) is a method used to compare and sort text that includes characters from all languages, ensuring consistent ordering worldwide. It assigns each character a specific sort level based on their language and script, considering factors like accents and special symbols. When comparing two strings, the algorithm checks these levels step-by-step to determine which should come first, making sorting culturally and linguistically accurate. This ensures that text data is ordered correctly across different languages and scripts, supporting global communication and data management.
