从字符串中删除ASCII符号 [英] Remove ASCII symbol from String

问题描述

我需要摆脱一个看起来像

如果您突出显示规格&选择查看选择来源，您会注意到，在单词（可选）之后，它将开始出现在第63行。

如何从String中删除此符号？如果可能的话，是否有办法排除一般的奇怪符号？

编辑2 。尝试两个建议的答案后，我仍然无法将其从String中删除。我现在看到的一个关键部分，我可能已经遗漏了，这个文本是从网站复制到Microsoft Excel中，然后被复制到一个Java Applet（TextArea）中，它被分析和分析。从...操纵。即使在文本区域不可见，它仍然保留在那里，当被复制回到Excel后。

测试代码是：

  String descript = textArea.getText（）; 
 descript = descript.replace（'\\\'，''）; 
 textArea.setText（descript）; 
  

将此文本重新导入Excel时，字符仍然保留。

解决方案

这是一个Unicode符号，因此要直接粘贴，您需要使用适当的编码（如UTF-8）编辑文件，您需要使用字体可以显示符号。

在Java字符串中，您可以随时使用Unicode转义来表示字符。男性符号是Unicode U + 2642，所以字符串将是：

 \\\♂
  

更新：查看网站您引用的字符实际上是一个垂直标签（VT）字符，Unicode U + 000B解释VT看到显示为内联。您可以使用

 \\\
  

为此。

使用类似

  String newString = oldString.replace（'\uBB'，''）; 
  

获取一个新的字符串，VT被空格替换。

I need to get rid of a character that looks exactly like the male ascii symbol from text - ♂. However, it's not the standard ASCII symbol, because if I paste it on StackExchange, it's displayed as indicated below:

How can I replace the character within a String? I've tried pasting the character directly into Eclipse but unfortunately that doesn't work (it looks exactly like the image above when pasted into Eclipse). You can see the symbol in Notepad++ however when using the search function:

Howevever, when displayed inline, it looks like this:

Edit: @Greg-449's answer, I've tried that but the character still remains in the String. I don't think it's the default character. I'll show you where you can reference it from a website:

Thermaltake: Chassis > Versa > Versa H21

If you highlight the specifications & choose View selection source you'll notice it start appearing on line 63 after the word (optional).

How can I remove this symbol from the String? If at all possible, is there a way to exclude strange symbols like that in general?

Edit 2. After trying both suggested answers, I'm still not able to remove it from the String. A critical part I now see that I may have left out is that the text is copied from the website, into Microsoft Excel, then into a Java Applet (TextArea) where it is analyzed & manipulated from. Even though not visible in the text area, it still remains there when copied back into Excel after being manipulated.

Code tested is:

String descript = textArea.getText();
descript = descript.replace('\u000B', ' ');
textArea.setText(descript);

When taking this text back into Excel, the character remains.

解决方案

This is a Unicode symbol so to paste it directly you need to be editing a file with a suitable encoding such as UTF-8 and you need to be using a font that can display the symbol.

In a Java string you can always use the Unicode escape to represent the character. The male symbol is Unicode U+2642 so the string would be:

"\u2642"

Update: Looking at the web site you reference the character is actually a 'vertical tab (VT)' character, Unicode U+000B which explains the 'VT' to see 'displayed inline'. You can use

"\u000B"

for this.

Use something like

String newString = oldString.replace('\u000B', ' ');

to get a new string with the VTs replaced by blanks.
