  * Standards are unclear in the usage of international currency
  * and monetary formats.
  * But I am expect that international currency symbol should be the first
  * (not depends upon where currency symbol situated in the national
  * format).
  *
  * If this isn't so, let's see:
  *       1 234.56 RUR
  *       GBP 1,234.56
  *       USD 1,234.56
  * The situation really is worse than you see above:
  * RUR typed wrong here---it prints '1 234.56 RUR ' (see space after RUR).
  * This is due to intl_fmp.curr_symbol() == "RUR ". (see reference in comments
