使用说明与常见问题How-to & FAQ

「截断 Unicode 文本」是什么？What is the Truncate Unicode tool?

按字素截断到最大长度，可选省略号（省略号计入长度）。本地处理。可设置「最大字素数」、「省略号」。Truncate to a maximum number of graphemes with an optional ellipsis, which counts toward the limit. Processed locally. Settings: Max graphemes, Ellipsis.

如何使用「截断 Unicode 文本」？How do I use the Truncate Unicode tool?

在「截断 Unicode 文本」中，把内容粘贴或输入到上方输入框，按需设置「最大字素数」、「省略号」，结果会实时显示在下方，点击「复制结果」即可复制。In the Truncate Unicode: Paste or type into the input box, adjust "Max graphemes", "Ellipsis"; the result appears below instantly — click "Copy result" to copy it.

省略号算在长度里吗？Does the ellipsis count toward the length?

算。例如 hello world、最大 5、省略号为 … 时结果是 hell…（共 5 个字素）；把省略号框清空则结果是 hello。不超过最大长度的文本原样保留，不加省略号。结果永远不会超过最大字素数：省略号不短于最大长度时只输出省略号的前几个字素（最大 3、省略号 .... 得到 ...；最大 0 得到空结果）。Yes. For example hello world with Max 5 and the ellipsis … gives hell…, five graphemes in total; with the Ellipsis box cleared it gives hello. Text that already fits is returned unchanged, with no ellipsis. The result never exceeds Max graphemes: when the ellipsis is at least as long as the maximum, only its first graphemes are output (Max 3 with the ellipsis .... gives ...; Max 0 gives an empty result).

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「截断 Unicode 文本」中输入 hello world，「最大字素数」设为 5，输出为：hell…。For example, the Truncate Unicode turns the input hello world, "Max graphemes" set to 5 into: hell….

有哪些选项可以调整？What options can I adjust?

「截断 Unicode 文本」的设置：「最大字素数」默认 10；「省略号」默认 …。每次生成结果都按当前设置处理。Settings in the Truncate Unicode — "Max graphemes" default 10; "Ellipsis" default …. The result always uses the current settings.
