String regex = "[\\p{InCJK Unified Ideographs}&&\\P{Cn}]]"; 在当前的 JDK 版中与 [\u4e00-\u9fa5] 的意义一致。但这样可以匹配 Java 平台所支持 Unicode 块名为 CJK Unified Ideogrpahs 中已定义的字符，这种方式就属于“活”代码 今后的 JDK 版本升级了，定义到了 \u9fa6 的字符，同样能够满足匹配。 6.2.6 establishing construction site welding secondary, secondary electrode consisted of Rod piled up, welding rod ovens, incubators, thermometers, hygrometers and backing of electrodes, receiving, payment and recovery system.
