Technical Background
Text case conversion involves Unicode character manipulation and string processing algorithms. The tool uses JavaScript's built-in string methods enhanced with custom logic to handle edge cases and special formatting rules. Title case conversion follows English language conventions, capitalizing the first letter of each significant word while keeping articles, prepositions, and conjunctions lowercase unless they appear at the beginning or end. Sentence case conversion identifies sentence boundaries using punctuation marks and applies capitalization accordingly. The implementation handles Unicode characters, preserves whitespace and formatting, and processes text efficiently regardless of length.
