Utf8.isWellFormed介绍

[英]Returns true if bytes is a well-formed UTF-8 byte sequence according to Unicode 6.0. Note that this is a stronger criterion than simply whether the bytes can be decoded. For example, some versions of the JDK decoder will accept "non-shortest form" byte sequences, but encoding never reproduces these. Such byte sequences are not considered well-formed.

This method returns true if and only if Arrays.equals(bytes, new does, but is more efficient in both time and space.
[中]如果字节是符合Unicode 6.0的格式良好的UTF-8字节序列，则返回true。请注意，这是一个比是否可以解码字节更严格的标准。例如，一些版本的JDK解码器将接受“非最短形式”字节序列，但编码永远不会复制这些字节序列。这样的字节序列被认为格式不好。
当且仅当数组为true时，此方法返回true。equals（字节，new有，但在时间和空间上都更有效。
