🔤 UTF-8 转 UTF-32Convert UTF-8 to UTF-32

使用说明与常见问题How-to & FAQ

「UTF-8 转 UTF-32」是什么？What is the Convert UTF-8 to UTF-32 tool?

把文本写成 UTF-32 码位十六进制（每个 8 位），可选大端/小端和 BOM（默认大端、无 BOM）。本地处理。Write the text as UTF-32 code points in hex (8 digits each), with a big-endian/little-endian choice and an optional BOM (default: big-endian, no BOM). Processed locally.

如何使用「UTF-8 转 UTF-32」？How do I use the Convert UTF-8 to UTF-32 tool?

在「UTF-8 转 UTF-32」中，把内容粘贴或输入到上方输入框，按需设置「字节序」，结果会实时显示在下方，点击「复制结果」即可复制。例如输入「Hi」，得到「00000048 00000069」。In the Convert UTF-8 to UTF-32: Paste or type into the input box, adjust "Byte order"; the result appears below instantly — click "Copy result" to copy it. Example: "Hi" → "00000048 00000069".

大端、小端和 BOM 怎么选？Which byte order and BOM should I choose?

默认大端（BE）、不加 BOM，例如 😀 = 0001f600。选小端（LE）时每个码位的 4 个字节顺序反过来（00f60100）。勾选 BOM 会在开头加 0000feff（大端）或 fffe0000（小端），方便接收方识别字节序。「UTF-32 转 UTF-8」工具按同样的规则读取。The default is big-endian (BE) without a BOM, e.g. 😀 = 0001f600. Little-endian (LE) reverses the 4 bytes of each code point (00f60100). Ticking BOM adds 0000feff (big-endian) or fffe0000 (little-endian) at the start so the receiver can tell the byte order. The UTF-32 to UTF-8 tool reads the same forms.

和「Unicode 转 UTF-32」有什么区别？How is this different from Unicode to UTF-32?

编码结果相同；本页属于 UTF-8 工具组，并提供字节序和 BOM 选项。The encoding is the same; this page belongs to the UTF-8 group and adds the byte-order and BOM options.

输入和输出是什么样的？What does the input and output look like?

例如在「UTF-8 转 UTF-32」中输入 Hi，输出为：00000048 00000069。For example, the Convert UTF-8 to UTF-32 turns the input Hi into: 00000048 00000069.

有哪些选项可以调整？What options can I adjust?

「UTF-8 转 UTF-32」的设置：「字节序」可选 大端 BE、小端 LE（默认 大端 BE）；可勾选：「开头加 BOM」、「每码位一行」、「大写」。每次生成结果都按当前设置处理。Settings in the Convert UTF-8 to UTF-32 — "Byte order": Big-endian (BE), Little-endian (LE) (default Big-endian (BE)); tick boxes: "Add a BOM", "One per line", "Uppercase". The result always uses the current settings.

编码和加密有什么区别？Is encoding the same as encryption?

编码（如 Base64、URL 编码）可直接还原，不提供保密性；加密需要密钥。「UTF-8 转 UTF-32」的处理全部在本地完成。No. Encoding (Base64, URL…) is reversible by anyone; encryption needs a key. The Convert UTF-8 to UTF-32 works fully offline in your browser.

「UTF-8 转 UTF-32」免费吗？需要注册吗？Is the Convert UTF-8 to UTF-32 free? Do I need an account?
