What case formats are supported?

The tool supports UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case.

Does it handle accented characters?

Technical specification

Algorithm or formula: String tokenisation into words, then case-specific joiners (camelCase capitalises every word after the first, snake_case lowercases and joins with underscores, kebab-case with hyphens, Title Case capitalises each word).
Browser API or library: Native String.prototype methods (toLowerCase, toUpperCase, split, replace) with Unicode-aware regex. No external library.
Input limits: Bounded by available browser memory. Multi-megabyte text strings convert without issue on modern devices.
Output: Plain text in the chosen case format, copyable to the clipboard.
Known limitations: Sentence-boundary detection is heuristic (period, exclamation, question mark). Acronyms inside camelCase are not preserved.
