Java中的Readline()无法正确处理中文字符
原标题:Readline() in Java does not handle Chinese characters properly

I have a text file with Chinese words written to a line. The line is surrounded with " ", and written using fileOutputStream.write(string.getBytes()).

我在阅读英语单词行时没有问题,我的缓冲阅读器用readLine()完美地解析了它。然而,它将中文句子识别为多行,从而打乱了我的程序流程。

有什么解决方案吗?

问题回答

使用string.getBytes()使用平台默认编码对string进行编码。这很少是您想要的,尤其是当您试图编写非当前区域设置的本地字符时。

请改为指定编码(使用string.getBytes(例如,”UTF-8“))。

一种更干净、更Java风格的方法是将OutputStream包装在OutputStreamWriter中,如下所示:

Writer w = new OutputStreamWriter(out, "UTF-8");

然后您只需拨打writer.write(字符串)并且不需要每次编写string时都重复编码。

并且,如下所述,在读取文件时指定相同的编码(最好使用Reader)。

如果您通过fileOutputStream.write(string.getBytes())输出文本,那么您将使用平台的默认编码输出文本。重要的是要确保您在阅读时使用适当的编码,并使用有编码意识的方法。问题不会出现在您的BufferedReader实例中,但无论您拥有什么Reader,都会将字节转换为字符。
