Good to know
Uppercase and lowercase follow the page language. Capitalize words uppercases the first letter of each word; it does not apply editorial title-case rules. Sentence case lowercases the text and capitalizes the first letter of each detected sentence. Review names, acronyms, and abbreviations afterward. Arabic letters have no uppercase or lowercase; Latin letters in mixed text still change. Spacing, punctuation, and emoji are preserved.
