How YouTube counts a post

YouTube accepts 5,000 characters in the body of one post, measured in UTF-16 code units, so an emoji usually costs two. This page applies the same rule our connector applies before it sends a post.

A link costs exactly the characters it occupies, so a long URL costs more of the ceiling than a short one.

這些數字描述的是哪種帳號

最保守的情況：一個新連線且未取得提升資格的帳號。有些平台會在頻道或企業通過驗證後提高上限，若有此情況，頁面會加以說明。

常見問題

How does YouTube count a character?

By UTF-16 code unit, which is what a programming language usually reports as string length. Most emoji cost two, and some cost more. This page measures with the browser segmenter and then applies the YouTube rule on top.

Do links count against the YouTube limit?

Yes, at their real length. A URL costs the characters it occupies, the same as any other text.

我的草稿會被上傳嗎？

不會。此檢查在你的瀏覽器中運作，沒有任何請求會帶走你的文字，不會儲存任何內容，關閉分頁就足以將它捨棄。

這個工具能幫我發布嗎？

目前還不行。尚無任何連接器完成供應商驗證，因此此網站目前尚未透過任何工具發布到任何平台。此頁面是限制檢查工具，而非撰寫工具。
