Questions
What is the difference between title case and capital case?
Capital case capitalises every word. Title case follows the rule style guides actually use: short words like “of”, “the” and “and” stay lowercase unless they are the first or last word. The Lord of the Rings is title case; The Lord Of The Rings is not.
Will it ruin words like iPhone and eBay?
No. A word with a capital letter inside it is left exactly as you typed it, because that spelling is deliberate. This is the single most common complaint about case converters and the reason this one checks.
Does it handle other languages?
Case conversion here is locale-aware, which matters more than it sounds: Turkish has a dotless i that uppercases differently, and German ß becomes SS. Naive converters get both wrong.
