        default currency format of the locale is chosen, and that new fixed
        currency codes are of course not converted to other currencies. The
        method may also be used as a general method taking, converting and
        inserting almost arbitrary format codes. To insert or use, for example,
        the default currency format code matching the current locale, the
        method could be called with<br/>

            was empty, could not be converted or has errors, the eLnge locale's
            standard number format is chosen instead. The index key is
            guaranteed to represent some valid number format. If

        might have been constructed using I18N locale data where a used locale
        of a currency format code must not necessarily match the locale of
        the locale data itself, e.g. [$HK$-40C] (being "zh_HK" locale) in
        zh_CN locale data. Here the rExtension would have the value 0x40c but
         eFormatLanguage of the number format would have the value of zh_CN
         locale, the value with which the corresponding CurrencyEntry is
        constructed.

            The language/country value of the format of which rSymbol and

             entries are checked.
        @return
            The matching entry if unique (in which case bFoundBank is set),
