Linux服务器上缺少货币符号

问题描述

我有一个需要显示货币符号的Java应用程序。我正在Linux（Ubuntu）服务器上运行。

在Linux服务器上LANG = en_GB.UTF-8

以下代码测试了该问题：

  import java.util.Currency; 
 import java.util.Locale; 
 import java.text.NumberFormat; 
 
公共类SymbolTest 
 {
 public static void main（String [] args）
 {
 System.out.println（ H​​ardcoded Unicode Currency Symbol为GBP [\u00A3]）； 
 System.out.println（带有区域设置[[+ Currency.getInstance（Locale.UK）.getSymbol（）+]的GBP的货币符号）； 
 System.out.println（带有区域设置[[+ Currency.getInstance（Locale.US）.getSymbol（）+]的美国货币符号）； 
 System.out.println（带有语言环境[[+ Currency.getInstance（Locale.FRANCE）.getSymbol（）+]的法国的货币符号）； 
} 
} 
  

给出输出：

GBP的硬编码Unicode货币

带有区域设置[£]的GBP的货币符号

具有区域设置[USD]的美国货币符号

具有区域设置[â]的法国的货币符号

我怀疑这是Ubuntu服务器上的Locale或Lang问题。
我应该在linux服务器上安装/配置什么以显示货币符号？

解决方案

您的程序是正确尝试输出UTF-8，但是您的终端显然不知道它应该处于UTF-8模式。所以您的终端在这里有问题。您使用的是什么终端？

尝试将程序的输出重定向到文件，并使用支持UTF-8的编辑器打开该文件，以验证输出是否正确。

I have a java application that needs to display currency symbols. I'm running on a Linux(Ubuntu) server.

On Linux server LANG=en_GB.UTF-8

The following code tests the problem:

import java.util.Currency;
import java.util.Locale;
import java.text.NumberFormat;

public class SymbolTest
{
  public static void main(String[] args)
  {
    System.out.println("Hardcoded Unicode Currency Symbol for GBP [\u00A3] ");
    System.out.println("Currency Symbol for GBP with Locale [" + Currency.getInstance(Locale.UK).getSymbol() + "]");
    System.out.println("Currency Symbol for US with Locale [" + Currency.getInstance(Locale.US).getSymbol() + "]");
    System.out.println("Currency Symbol for FRANCE with Locale [" + Currency.getInstance(Locale.FRANCE).getSymbol() + "]");
  }
}

gives the output:

Hardcoded Unicode Currency Symbol for GBP £

Currency Symbol for GBP with Locale [£]

Currency Symbol for US with Locale [USD]

Currency Symbol for FRANCE with Locale [â¬]

I suspect this is a Locale or Lang problem on the Ubuntu server.What should I install/configure on the linux server to enable the currency symbols to display?

解决方案

Your program is correctly trying to output UTF-8, but your terminal apparently doesn't know that it's supposed to be in UTF-8 mode. So your terminal is at fault here. What terminal are you using?

Try redirecting the output of the program to a file and open that file with a UTF-8 capable editor to verify that the output is correct.
