平台默认字符编码如何影响跨平台性能 [英] How does the platform default character encoding affect cross platform performance

问题描述

我已经阅读了它的坏主意，使用平台默认字符编码，例如当读取文本文件和将文本导入数组等。你能解释一下如何可以影响跨平台的性能，以及如何克服这个问题？是否有应用于跨平台应用程序的编码？感谢

I have read that its bad idea to use platform default character encoding for example when reading a text file and importing the text into arrays etc. Could you explain how that could affect cross platform performance , and how to get past that problem ? Is there an encoding that should be used for cross-platform applications ? Thanks

推荐答案

这不是关于性能，而是关于显示和阅读正确编码的文本。有多种方法可以解决此问题：

It's not about performance, but about showing and reading properly encoded text. There are a number of ways to cope with the problem:

• 设置JVM选项 -Dfile.encoding = utf -8


• 始终使用重载了字符编码参数的方法。这些是 String ， Reader ， Writer 和更多。

• set a JVM option -Dfile.encoding=utf-8
• always use the methods overloaded with a character encoding parameter. These are the ones of String, Reader, Writer and more.

我认为后者是必须的。如果你总是设置jvm选项，它会工作，但如果你忘记设置它在某一点，将在随机的地方出现意想不到的失败。

I think the latter is a must. If you always set the jvm option, it will work, but if you forget to set it at some point, there will be unexpected failures at random places.

问题 - 坚持使用UTF-8。

And the other question - stick to UTF-8.
