Frequently asked questions
How does Title Case handle small words?
Every word is capitalized, including short words. Different style guides disagree about words like “of” and “the” — if your style guide requires them lowercase, use Sentence case and fix those few words by hand.
Does the converter handle accented characters?
Yes — it uses Unicode-aware case mapping, so characters like é, Ñ and Ω convert correctly, not just A–Z.
