使用Java从文件中读取特殊字符？

Question

I am using java to read a text file and which has some special chars like Yen(¥) . I have not specified any encoding/charset while reading a file and is working fine in windows. But if i deploy the same in unix machine then ¥ is replaced by ' ? '. Now i am going to specify charset windows-1252 to avoid the issue. will windows-1252 work on unix/linux boxes? My unix box charset is set to ' utf-8 '. am using below the code:

LineIterator iterator =FileUtils.lineIterator(*filename*,"Windows-1252");

Answer 1

The class StandardCharsets gives you a list of encodings / charsets that are "guaranteed to be available on every implementation of the Java platform."

This list doesn't contain the Windows encodings but for most common Java versions on Windows, Mac and Linux, Cp1251 is available.

Note that you'll get a UnsupportedCharsetException or UnsupportedEncodingException when it's not available, so the code above is safe (in the sense that it won't produce garbage).

If you want to be really safe, the common approach is to use only UTF-8 encoded data in your projects.

如果我正确理解了您的问题，通常可以通过使用文本编辑器将文本文件保存为UTF-8编码，然后从Java程序打开该文件时再次指定UTF-8来解决此问题。
