Unicode-aware

Case conversion works with accented letters and non-Latin scripts: “émile” becomes “ÉMILE”. Title Case keeps short words such as “and” and “of” lowercase unless they start the title.

Programming cases

camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE turn each line into one identifier, splitting on spaces, punctuation and existing case changes.
