注:上图中的Unicode range为Unicode码点值范围(也就是Unicode码点编号范围),Hex为16进制,Binary为二进制;Encoded bytes为UTF-8编码中各字节的编码方式(即编码算法),其中,x代表Unicode二进制码点值的单字节或低字节中的低7位或8位、y代表两字节码点值的高字节中的低3位或8位以及三字节码点值的中字节中的8位、...
Hex为16进制,Binary为二进制;Encoded bytes即UTF-8编码中各字节的编码方式(即编码算法),其中,x代表Unicode二进制码点值的单字节或低字节中的低7位或8位、y代表两字节码点值的高字节中的低3位或8位以及三字节码点值的中字节中的8位、z代表三字节码点值的高字节中的低5位。
Characters from many languages and scripts can be represented by the widely used UTF-8 character encoding. To ensure that text appears correctly when displayed or processed by a computer or application, the UTF-8 decoder reads and maps the binary data in a UTF-8 encoded file or stream to ...
