FAQ
Why is my count different from Microsoft Word?
Word counts characters differently. It may include certain symbols or handle mixed Chinese-English text differently.
How are full-width and half-width characters counted?
Full-width English letters and numbers are counted as "Chinese Characters" because they occupy the same display width and bytes as Chinese.
How are emoji counted?
Emoji are included in total character count, typically 4 bytes each. They are not categorized as Chinese or English.
Are line breaks counted?
Line breaks are included in total character count but not in Chinese or English character counts. Paragraphs are counted by blank line separators.
