Java : Skip Unicode characters while reading a file

Question

我正在使用以下代码读取文本文件，

try (BufferedReader br = new BufferedReader(new FileReader(<file.txt>))) {
   for (String line; (line = br.readLine()) != null;) {
      //I want to skip a line with unicode character and continue next line
      if(line.toLowerCase().startsWith("\\u")){
            continue;
         //This is not working because i get the character itself and not the text 
        }
    }
}

如何在读取文件时跳过所有 unicode 字符？

Answer 1

您可以跳过所有包含非 ASCII 字符的行:

if(Charset.forName("US-ASCII").newEncoder().canEncode(line)){
    continue; 
}
