「八进制字节转 UTF-8」是什么？What is the Convert Octal to UTF-8 tool?
把八进制字节序列（0–377）按 UTF-8 解码成文本。本地处理。Decode a sequence of octal bytes (0–377) as UTF-8 text. Processed locally.
如何使用「八进制字节转 UTF-8」？How do I use the Convert Octal to UTF-8 tool?
在「八进制字节转 UTF-8」中，把内容粘贴或输入到上方输入框，结果会实时显示在下方，点击「复制结果」即可复制。例如输入「110 151」，得到「Hi」。In the Convert Octal to UTF-8: Paste or type into the input box; the result appears below instantly — click "Copy result" to copy it. Example: "110 151" → "Hi".
每个值的范围是多少？What range can each value have?
每个值是一个字节，八进制 0–377（十进制 0–255）。位数不限，前导零可以，例如 0110 和 110 都是 72（H）。Each value is one byte: 0–377 in octal (0–255 in decimal). Any number of digits is accepted and leading zeros are fine, so 0110 and 110 are both 72 (H).
输入有错时会提示什么？What do the error messages tell me?
会指出是第几个值、原样引用它，并说明是哪个字符不是八进制数字（0–7），或数值超过 377；字节不是有效 UTF-8 时给出第一个出错字节的位置和原因。They name the value by position, quote it and say which character is not an octal digit (0–7) or that it is above 377. If the bytes are not valid UTF-8, the first bad byte is reported with its position and the reason.
开头的 BOM 会怎样？What happens to a leading BOM?
开头的 357 273 277（UTF-8 BOM）会被去掉，结果下方会注明。A leading 357 273 277 (the UTF-8 BOM) is removed and a note says so.
输入和输出是什么样的？What does the input and output look like?
例如在「八进制字节转 UTF-8」中输入 110 151，输出为：Hi。For example, the Convert Octal to UTF-8 turns the input 110 151 into: Hi.
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。「八进制字节转 UTF-8」的处理全部在本地完成。No. Encoding (Base64, URL…) is reversible by anyone; encryption needs a key. The Convert Octal to UTF-8 works fully offline in your browser.
「八进制字节转 UTF-8」免费吗？需要注册吗？Is the Convert Octal to UTF-8 free? Do I need an account?
