Useful details
Uppercase and lowercase use JavaScript Unicode casing. Title case capitalizes a letter after a non-letter/non-number boundary. Sentence case capitalizes the first letter and a letter after sentence punctuation followed by whitespace. These are mechanical rules, not grammatical or language-specific editing. Acronyms, names and abbreviations may need manual correction. Input is limited to two million characters.
