字符统计

功能说明What It Does

字符统计是一款面向开发者与写作者的在线工具，可实时计算字符数、单词数、行数、段落数，并区分中英文、标点与空白。

A character counter built for developers and writers — it counts characters, words, lines and paragraphs in real time, distinguishing Chinese/English, punctuation and whitespace.

除常规统计外，它还支持 UTF-8 / GBK 字节数计算、代码行与注释行识别、字符频率分析、正则匹配与长度校验。

Beyond basics, it computes UTF-8 / GBK byte size, recognizes code vs comment lines, analyzes character frequency, and supports regex matching and length checks.

适合接口字段长度核对、SEO 标题与描述字数检查、文案排版与代码审查等场景。

Great for checking API field lengths, SEO title/description character counts, copy layout and code review.

输入即出结果，统计口径清晰，避免不同编辑器字数统计不一致的困扰。

Results appear as you type with a clear counting standard, avoiding the inconsistencies between editors.

适用人群Who Should Use

开发者与测试工程师，需要核对接口字段字节长度、代码行数与字符集限制。

Developers and QA engineers who need to check API field byte lengths, code line counts and charset limits.

内容编辑、运营与 SEO 从业者，需要精确控制标题与正文的字数。

Editors, operators and SEO practitioners who need precise character control over titles and body text.

技术原理How It Works

通过遍历字符串与正则表达式统计字符、单词、行与段落，并区分中英文与空白。

Counts characters, words, lines and paragraphs by scanning strings with regex, distinguishing Chinese/English and whitespace.

字节数依据 UTF-8 / GBK 编码规则计算，全部在浏览器本地完成。

Byte size is computed per UTF-8 / GBK encoding rules, all in the browser.

安全与隐私Privacy & Security

所有文本仅在本机处理，不上传服务器，无需担心内容泄露。

All text is processed on-device and never uploaded, so there is no risk of leaking content.

使用步骤How to Use

1. 在输入框粘贴或输入文本。Paste or type your text.
2. 实时查看字符 / 单词 / 行数等统计结果。View live char / word / line stats.
3. 切换字节编码（UTF-8 / GBK）查看字节数。Switch encoding to check byte size.
4. 需要时使用正则匹配或长度校验功能。Use regex match or length check if needed.
