What is included in the character count?
The total includes every character in the text, including spaces, punctuation, tabs, and line breaks. “Characters without whitespace” removes all whitespace, not just the ordinary space between words. This makes it useful when a service excludes whitespace from its limit.
The count follows JavaScript string length. Most letters count as one; some emoji and combined Unicode symbols can count as more than one code unit, so a platform with its own counter may show a different total.
