「旋转 Unicode 文本」是什么？What is the Rotate Unicode tool?
把文本按字素旋转（循环左移，负数为右移）。本地处理。可设置「旋转量（字素）」。Rotate text by graphemes (cyclic left shift; a negative amount shifts right). Processed locally. Settings: Rotate by (graphemes).
如何使用「旋转 Unicode 文本」？How do I use the Rotate Unicode tool?
在「旋转 Unicode 文本」中，把内容粘贴或输入到上方输入框，按需设置「旋转量（字素）」，结果会实时显示在下方，点击「复制结果」即可复制。In the Rotate Unicode: Paste or type into the input box, adjust "Rotate by (graphemes)"; the result appears below instantly — click "Copy result" to copy it.
旋转是怎么算的？How does rotation work?
正数把开头的字素移到末尾（ABCD 旋转 1 得 BCDA），负数反过来（旋转 -1 得 DABC）；超过长度时按长度取余。A positive amount moves graphemes from the start to the end (ABCD rotated by 1 gives BCDA) and a negative amount does the opposite (by -1 gives DABC). Amounts larger than the length wrap around.
什么是字素（字素簇）？What is a grapheme (grapheme cluster)?
字素（字素簇）就是看到的一个字符，它可能由好几个码位组成：例如 é 可以是 e 加一个组合重音符，👨👩👧 是用零宽连接符连起来的 5 个码位，🇹🇼 是两个区域指示符。本页按 Unicode 规则（UAX #29，即浏览器的 Intl.Segmenter）切分字素，所以这些都算 1 个，不会被拆开。A grapheme (grapheme cluster) is one user-perceived character, which can be made of several code points: é can be e plus a combining accent, 👨👩👧 is five code points joined by zero-width joiners, and 🇹🇼 is two regional indicators. This page splits graphemes with the Unicode rules (UAX #29, the browser's Intl.Segmenter), so each of these counts as 1 and is never broken apart.
输入和输出是什么样的？What does the input and output look like?
例如在「旋转 Unicode 文本」中输入 ABCD，「旋转量（字素）」设为 1，输出为：BCDA。For example, the Rotate Unicode turns the input ABCD, "Rotate by (graphemes)" set to 1 into: BCDA.
有哪些选项可以调整？What options can I adjust?
「旋转 Unicode 文本」的设置：「旋转量（字素）」默认 1。每次生成结果都按当前设置处理。Settings in the Rotate Unicode — "Rotate by (graphemes)" default 1. The result always uses the current settings.
处理大段文本会卡吗？Can it handle long text?
「旋转 Unicode 文本」在浏览器中直接处理，几 MB 以内的文本通常瞬间完成；文本不会离开你的设备。The Rotate Unicode runs in your browser; text up to a few MB is usually processed instantly and never leaves your device.
「旋转 Unicode 文本」免费吗？需要注册吗？Is the Rotate Unicode free? Do I need an account?
「旋转 Unicode 文本」完全免费，无需注册或安装，打开网页即可使用，手机和电脑都能用；输入的内容只在你的浏览器本地处理。The Rotate Unicode is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
