Answer 1

使用 UTF-8 编码。

\n\n

您可以全局设置它：

\n\n

java -Dfile.encoding=UTF-8\n

\n\n

或者本地：

\n\n

System.setProperty("file.encoding", "UTF-8");\n\nbyte inbytes[] = new byte[1024];\nFileInputStream fis = new FileInputStream("the.location.of.your.cookie");\nfis.read(inbytes);\n

\n\n

另外，如果您手动编辑 cookie，请勿保存 \xc3\x84。而是使用 UTF-8 等效项，即

\n\n

System.out.println("\\u00c4");\n\n\n\nChars   Unicode\n------------------------------\n\xc3\x84, \xc3\xa4    \\u00c4, \\u00e4\n\xc3\x96, \xc3\xb6    \\u00d6, \\u00f6\n\xc3\x9c, \xc3\xbc    \\u00dc, \\u00fc\n\xc3\x9f       \\u00df\n
