Surrogate pairs & mixed input
Characters above U+FFFF (like 🚀 U+1F680) are encoded as a surrogate pair — two \uXXXX escapes that together represent one code point, exactly how JavaScript source expects them. The reverse pass understands mixed formats in one input: \u0048, U+0048, 0x48, H and H, separated by spaces or nothing at all.
如何使用Unicode 转换器
粘贴任意字符，三种视角同时给出：U+ 码点、字符名称、UTF-8 与 UTF-16 字节序列。\uXXXX、\u{...}、\xXX 三种转义风格双向解析，表格模式把整串文本逐字符拆开。
它更是隐形字符的排查入口：零宽空格、不换行空格、软连字符在编辑器里长得一模一样，却会让路由、校验和 diff 全部失灵。把可疑文本粘进来，冒充者当场报出姓名。
