我發現手機上顯示的貨幣符號跟實際遇到的可能不同，爲此我逐一查詢了不一樣國家/地區的顯示。大部分是肯定的，有幾個國家不太肯定。java

最開始我用 Java 代碼來獲取，發現並不許確，好比菲律賓，官方有英語和菲律賓語，我都試了，獲得都是 PHP xxx，PHp xxx 不符合預期。代碼以下：android

package com.tutorialspoint;

import java.util.*;
import java.text.SimpleDateFormat;
import java.text.DecimalFormat;
import java.text.DecimalFormatSymbols;
import java.text.NumberFormat;
import java.util.Locale;

public class CurrencyDemo {
   public static void main(String args[]) {
        /*
      // create a currency object with specified locale
      Locale locale = Locale.GERMANY;
      Currency curr = Currency.getInstance(locale);

      // print currency's code
      System.out.println("Locale's currency code:" + curr.getCurrencyCode());
      */
      
      
        
        double number = 123456.789;
        
        // https://developer.android.com/reference/java/util/Locale#fields_2
        Locale[] locales = {
            Locale.CANADA, 
            Locale.CANADA_FRENCH,
            Locale.CHINA,
            Locale.FRANCE,
            Locale.GERMANY,
            Locale.ITALY, 
            Locale.JAPAN,
            Locale.KOREA,
            Locale.PRC,
            Locale.SIMPLIFIED_CHINESE,
            Locale.TAIWAN,
            Locale.TRADITIONAL_CHINESE,
            Locale.UK,
            Locale.US,
            new Locale("en", "IN"),
            new Locale("en", "CA"),
            new Locale("zh", "HK"),
            new Locale("zh", "MO"),
            new Locale("zh", "SG"),
            new Locale("en", "SG"),
            new Locale("th", "TH"),
            new Locale("vi", "VN"),
            new Locale("ja", "JP"),
            new Locale("ga", "IE"),
            new Locale("ms", "MY"),
            new Locale("fil", "PH"),
            new Locale("en", "AU"),
            new Locale("km", "KH"),
            new Locale("id", "ID"),
            new Locale("es", "ES"),
        };
        
        // locales = SimpleDateFormat.getAvailableLocales();

        for (int i = 0; i < locales.length; i++) {
            // Gets currency's formatted value for each locale
            // without change the currency symbol
            DecimalFormat formatter = (DecimalFormat) NumberFormat.getCurrencyInstance(locales[i]);
            String before = formatter.format(number);
            
            System.out.println(locales[i].getDisplayCountry() + " | before: " + before);
        }
   }
}
