What does this code do?

  • "[^\\u4e00-\\u9fa5\\w]" : Java Regex format, can find special symbols.
  • matcher.replaceAll("") : Replace thos special symbols with empty character.

这段代码的作用：

  • "[^\\u4e00-\\u9fa5\\w]" : Java 格式的正则表达式，用来匹配除了汉字、字母和数字以外的特殊字符
  • matcher.replaceAll("") : 用空字符替换掉找到的特殊字符。
