FAQ
Why can grapheme count and code point count differ?
Emoji and combining sequences can use multiple internal code points while appearing as one visible character.
Is my text sent to a server?
No. Counting runs entirely in your browser.
Is full-width equivalent exact?
No. It is an estimate. By default, ASCII is 0.5 and non-ASCII is 1.0.
Can I count selected text only?
Yes. Select text in the editor and the selection count will appear.
