Answer 1

I don't see any easy way to do this. Here's what I came up with...

The key to getting the actual currency symbol seems to be passing the destination locale into Currency.getSymbol:

currencyFormat.getCurrency().getSymbol(locale)

Here's some code that seems like it mostly works:

public static String formatPrice(String price, Locale locale, String currencyCode) {

    NumberFormat currencyFormat = NumberFormat.getCurrencyInstance(locale);
    Currency currency = Currency.getInstance(currencyCode);
    currencyFormat.setCurrency(currency);

    try {
        String formatted = currencyFormat.format(NumberFormat.getNumberInstance().parse(price));
        String symbol = currencyFormat.getCurrency().getSymbol(locale);

        // Different locales put the symbol on opposite sides of the amount
        // http://en.wikipedia.org/wiki/Currency_sign
        // If there is already a space (like the fr_FR locale formats things),
        // then return this as is, otherwise insert a space on either side
        // and trim the result
        if (StringUtils.contains(formatted, " " + symbol) || StringUtils.contains(formatted, symbol + " ")) {
            return formatted;
        } else {
            return StringUtils.replaceOnce(formatted, symbol, " " + symbol + " ").trim();
        }
    } catch (ParseException e) {
        // ignore
    }
    return null;
}
