ICU Probe All Currency Symbols

Is there a way to probe the ICU library for all UChar's representing currency symbols supported by the library?

My current solution is iterating through all locales and for each locale, doing something like this:

const DecimalFormatSymbols *formatSymbols = formatter->getDecimalFormatSymbols();
UnicodeString currencySymbol = formatSymbols->getSymbol(DecimalFormatSymbols::kCurrencySymbol);

The开发者_开发知识库n saving off each UChar in currencySymbol into a map (so no duplicates).

All currency symbols have the category Sc (Symbol, Currency), so you can just enumerate all characters from that category.

#include <cstdio>
#include <icu/unicode/uchar.h>

UBool print_all_currency_symbols(const void* context, UChar32 start, UChar32 limit, UCharCategory type) {
    if (type == U_CURRENCY_SYMBOL) {
        for (UChar32 c = start; c < limit; ++ c)
            printf("%04x\n", c);
    }
    return TRUE;
}

int main() {
    u_enumCharTypes(print_all_currency_symbols, NULL);

        return 0;
}
