UTF-16造句

Unicode defines character encodings in three distinct sizes-utf-8, UTF-16, and utf-32-while the traditional character type is 8 bits.

UTF-16BE: 16-bit UCS Transformation format, big-endian byte order.

UTF-16LE: 16-bit UCS Transformation format, little-endian byte order.

When supplementary characters are involved, a supplementary is counted as two UTF-16 code units using CODEUNITS16, or one UTF-32 code unit using CODEUNITS32.

However, if you use UTF-16, the size of the original document roughly doubles and the document takes longer to parse.

使用增补字符时，对于一个增补字符，使用CODEUNITS16 计算是两个UTF-16代码单元，而使用CODEUNITS32 计算则是一个UTF-32代码单元。

比方说，如果UTF-16数据原样加载到C字符串中，字符串可能从第一个ASCII字符的第二个字节截断。
