FAQ

How are words counted for mixed Chinese-English?
Chinese per character (1 Han = 1 word), English per word (space-separated). Mixed: rules added per language. "Hello 世界" = 1 word + 2 chars = 3 words. Chinese social platforms (WeChat, Weibo) typically follow this mixed rule.
Characters vs bytes?
Character is abstract (1 Han = 1 char). Byte is storage (UTF-8: 1 Han = 3 bytes). DB field lengths are typically bytes (VARCHAR(255) holds about 85 Chinese chars). Social platforms typically use characters.
How are Weibo 140 chars counted with links?
Weibo rule: pure Chinese by char count; URL shortened to 19 chars regardless; @username by char count; #topic# including two # by char. The "Weibo" mode approximates (URLs as 19). Best confirmed by testing in the Weibo editor.
What is Xiaohongshu’s recommended length?
No hard limit (1000-char posts work), but algorithm favors 800-1500 chars (excluding emoji and newlines). Title within 20 chars, paragraphs of 3-5 lines best. The "Xiaohongshu" mode hints accordingly.
What Flesch-Kincaid score is good for English?
Flesch Reading Ease: 60-70 general audience (news), 90+ very easy (children’s books), <30 academic. Flesch-Kincaid Grade Level: 6-9 middle school (mass content), 10-13 high school (popsci). Chinese has no standardized readability — English mode is reference only.

Use cases

  • WeChat / Weibo content: compare against platform limits before publishing
  • Xiaohongshu posts: title and body length optimization
  • SEO articles: long-tail keyword posts at 800-2000 chars
  • Email body: business emails concise (within 200 chars)
  • Essays / reports: meeting word count requirements

Use cases

Social media content, SEO articles, emails, essays. Ops, content creators, SEO, students, copywriters. CJK-English smart, byte dual-display, platform limits, reading time are the differentiators.
