FAQ

Is my data sent to a server?

No. All processing happens in your browser, so your text is never transmitted externally.

Are spaces counted in the character count?

The 'chars' count includes spaces. The 'chars (no spaces)' count excludes spaces, tabs, and newlines.

How is half-width vs full-width determined?

Characters with Unicode code points U+007F or below are counted as half-width; U+0080 and above as full-width. ASCII letters, digits, and symbols are half-width.

How are words counted?

Tokens separated by whitespace (spaces, tabs, newlines) are counted as words. Japanese word boundary detection is not supported.

What encoding is used for the byte count?

Bytes are counted in UTF-8. ASCII characters are 1 byte; Japanese characters (hiragana, kanji) are typically 3 bytes.
