Gangedan romanisation

Gangedan is written with Chinese characters, but this romanisation scheme was developed in 1998 by Gangedan State Council.

Overview
The romanisation scheme for Gangedan was developed in 1998 for use in the government publications printed in Gangedan using Latin script. Chinese characters are still widespread.

An interesting feature is that the single vowel indicates vowel nasalisation, while a double vowel indicates a non-nasal vowel. This is unusual for other romanisation systems.

Hiatus is marked with a diaeresis, e.g. teök35 (priority). The diaeresis indicates that two vowels should be pronunced separately, rather than as a diphtong.

Tones, however not marked by diacritics or tone spelling but simply put the superscript values of the Chao's tone lettering system.
