This page claims that the code mk or mkd stands for FYROM. The ISO 3166 says the mkd code is in fact Macedonia, the former Yugoslav Republic of (http://userpage.chemie.fu-berlin.de/diverse/doc/ISO_3166.html). The same goes for both the Name and the ISOCurrencySymbol
However the RegionInfo class for mk/mkd returns "Macedonia (FYROM)" which is more in line with the ISO standard. So the actual problem is with this page and I wonder if somebody intentionally changed it due to personal issues with the name of the country that bears the mkd code.
