使用说明与常见问题How-to & FAQ
「任意进制转 UTF-8 文本」是什么？What is the Convert Arbitrary Base to UTF-8 tool?
把按指定进制（2–36）写成的字节序列解码成 UTF-8 文本，每个字节都严格校验。本地处理。Decode a byte sequence written in a chosen base (2 to 36) into UTF-8 text, strictly checking every byte. Processed locally.
如何使用「任意进制转 UTF-8 文本」？How do I use the Convert Arbitrary Base to UTF-8 tool?
在「任意进制转 UTF-8 文本」中，把内容粘贴或输入到上方输入框，按需设置「进制 (2–36)」，结果会实时显示在下方，点击「复制结果」即可复制。In the Convert Arbitrary Base to UTF-8: Paste or type into the input box, adjust "Base (2–36)"; the result appears below instantly — click "Copy result" to copy it.
输入格式有什么要求？What input format is expected?
每个字节用空格、逗号或分号分开，每个字节必须完全由该进制的数字组成，值在 0–255 之间；16、8、2 进制可以带 0x、0o、0b 前缀。像 4G、1.5、12x 这样的字节会报错并指出是哪一个，不会只取前面能读的部分。Separate bytes with spaces, commas or semicolons. Each byte must consist only of digits of the chosen base and be 0 to 255; base 16, 8 and 2 also accept the 0x, 0o and 0b prefixes. Bytes such as 4G, 1.5 or 12x are rejected with the offending one quoted, rather than reading just the leading part.
为什么提示不是有效的 UTF-8？Why does it say the bytes are not valid UTF-8?
每个字节都读出来了，但它们组合起来不是合法的 UTF-8 序列，例如多字节字符缺了后续字节。Every byte was read, but together they do not form a valid UTF-8 sequence, for example a multi-byte character is missing its continuation bytes.
输入和输出是什么样的？What does the input and output look like?
例如在「任意进制转 UTF-8 文本」中输入 48 69，「进制 (2–36)」设为 16，输出为：Hi。For example, the Convert Arbitrary Base to UTF-8 turns the input 48 69, "Base (2–36)" set to 16 into: Hi.
有哪些选项可以调整？What options can I adjust?
「任意进制转 UTF-8 文本」的设置：「进制 (2–36)」默认 16。每次生成结果都按当前设置处理。Settings in the Convert Arbitrary Base to UTF-8 — "Base (2–36)" default 16. 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。「任意进制转 UTF-8 文本」的处理全部在本地完成。No. Encoding (Base64, URL…) is reversible by anyone; encryption needs a key. The Convert Arbitrary Base to UTF-8 works fully offline in your browser.
「任意进制转 UTF-8 文本」免费吗？需要注册吗？Is the Convert Arbitrary Base to UTF-8 free? Do I need an account?
「任意进制转 UTF-8 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 Convert Arbitrary Base to UTF-8 is completely free with no sign-up or install and works on phones and desktops; what you enter is processed only in your browser.
