BGN/PCGN 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 "Introduction to Romanization Systems and Roman script spelling conventions (updated 25 September 2020)" document, available at BGN and PCGN.
