JSON 指定“任何 UNICODE 字符”？
也许这只是我对unicode的不熟悉，所以如果我错了，请纠正我。
查看 http://json.org/，规范规定字符串可以包含“任何 UNICODE 字符”，但是这让我很困惑。
- JSON是一种通信格式 正确的？其核心是， 一切都必须转化为 字节。
- 相比之下，UNICODE 是 逻辑格式并且必须编码为 可以传送的吧？
那么他们的意思是什么？
Maybe this is just my unfamiliarity with unicode, so please correct me if I'm mistaken.
Looking at http://json.org/, the spec says that a string can include "any UNICODE character", but this confuses me.
- JSON is a communication format
correct? At the core of it,
everything must translate down to
bytes. - In contrast, UNICODE is a
logical format and must be encoded to
be able to transmit it, right?
So what did they mean there?

来自 RFC：
3. Encoding JSON text SHALL be encoded in Unicode. The default encoding is UTF-8. Since the first two characters of a JSON text will always be ASCII characters [RFC0020], it is possible to determine whether an octet stream is UTF-8, UTF-16 (BE or LE), or UTF-32 (BE or LE) by looking at the pattern of nulls in the first four octets. 00 00 00 xx UTF-32BE 00 xx 00 xx UTF-16BE xx 00 00 00 UTF-32LE xx 00 xx 00 UTF-16LE xx xx xx xx UTF-8From the RFC:

JSON is a serialization format which can include UNICODE characters. The byte representation of this unicode string is usually sent over the wire, normally through the HTTP protocol which uses HTTP headers to specify the encoding to the client which is UTF-8.
您是对的，所有内容都必须转换为字节，并且通常通过 UTF（Unicode 转换格式）进行。 JSON RFC 在 第 3 节中解释了如何判断 UTF 是什么用过的。
You're correct that everything must translate into bytes, and usually that usually occurs through a UTF (Unicode Transformation Format). The JSON RFC explains in section 3 how to tell what UTF is being used.
