Frequently asked questions

Does it work with Arabic?

Arabic has no upper or lower case, so case changes leave Arabic letters unchanged. The developer formats (snake_case, kebab-case) still work on Arabic words.

Which words stay lowercase in Title Case?

Short English articles, conjunctions and prepositions (a, an, the, and, or, of, to, in, on, for…) stay lowercase unless they are the first or last word.
