Different locales also return different versions of the same symbol. The US locale (en_US) returns a full-width ¥ symbol, where as the Japan locale (ja_JP) returns a regular ¥ symbol. Similarly, the French locale (fr_FR) will return a non-breaking space between the digits and the symbol, where as the French Canadian locale (fr_CA) which formats numbers the same way (“15,00 $NZ”, like above) uses a regular space.
