Which spelling(s) should be allowed, Tom? The Saudi Riyal has a 'y' in the middle, the Omani Rial doesn't. There is also a Ryal, but I can't remember where that's used. And the Cambodian Riel is spelled with an 'e'. All derivatives of the old Spanish 'real' I believe.
I wouldn't worry too much about a word not being in Ninja; All reliable dictionaries include both forms. Whether they should be common is another matter.
The Krona is Swedish, but the Krone is Danish and Norwegian. I wonder if the various plurals, 'kroner', 'kronor' and 'kronur' are also allowed in Chi?
