UN systems

Each title of a language or a writing system is followed by a note on the appropriate romanization system used (UN = United Nations, BGN/PCGN = US Board on Geographic Names and Permanent Committee on Geographical Names for British Official Use)

The systems listed here are ordered according to the Romanization examples exhibition poster at the 10th UNCSGN conference, from the UNGEGN Working Group on Romanization Systems.
