currency-cny is the same as currency-jpy. Shouldn't this be an alias instead? There are a few more duplicate icons that I had noticed but I don't remember which.
This is intentional, possibly to prepare for a time when Chinese Yuan and Japanese Yen no longer share the same symbol.
One use case for including it as both CNY & JPY is to avoid the need for conditionals in your code.
