Eclipse字符编码 [英] Eclipse character encoding

问题描述

我使用Scanner在Java中扫描.txt文档。但是，当我在Eclipse中打开.txt文档时，我注意到一些字符未被识别，并且它们被替换为类似这样的东西：

p>

这些字符甚至不会让我将文件扫描为

  while （scan.hasNext）
  

自动返回false（如果这些字符不存在，文档很好）。

那么，如何让Eclipse识别这些字符，以便我可以扫描？我无法手动删除它们，因为文档相当大。
感谢。

解决方案

您正在阅读的文件必须包含UTF-8或其他编码字符，尝试打印他们在控制台，那么你会得到一些chracters作为 '。这是因为defualt控制台编码不是eclipse中的UTF-8。您需要通过在下拉菜单中运行配置 - >常用 - >编码 - >选择UTF-8进行设置。检查belo屏幕截图：

/ p>

I am using Scanner to scan a .txt document in Java. However, when I open the .txt document in Eclipse, I notice some characters are not being recognized, and they are replaced with something that looks like this:

�

These characters won't even let me scan the file as

    while(scan.hasNext)

automatically returns false (if these characters are not present, then I can scan the document just fine).

So, how do I get Eclipse to recognize these characters so I can scan? I can't manually remove them because the document is quite large. Thanks.

解决方案

The file you are reading must be containg UTF-8 or some other encoding characters and when you try to print them on on console then you will get some chracters as �'. This is because the defualt console encoding is not UTF-8 in eclipse. You need to set it by going to Run Configuration -> Common -> Encoding -> Select UTF-8 formthe drop down. Check belo screenshot:
