json - JSON encoding details

Question

I was reading JSON's succinct language specification and got surprised for this sentence:

Excepting a few encoding details, that completely describes the language.

What are the details which can break those simple rules.

Answer 1

有关完整规范，请参阅RFC 4627。具体与编码有关：

JSON 文本应以 Unicode 编码。默认编码为 UTF-8。

如果您的文本不是 Unicode，则它不是 JSON。
