Itanigawan alphabet

Itanigawan, official in Itanigawa state of Gooperland, has been written with Latin alphabet since the 1970s (and also between 1916 and 1938 during Latinisation of Gooperland).

History

 * Before 1916: Thai alphabet is used in Itanigawan language.
 * 1916: Latin-based alphabet began to be official in Itanigawan.
 * 1938: Along with the other Latinised alphabets (except Irish, Italian and French languages) of the United States of Gooperland, Japan banned the Itanigawan Latin alphabet along with the language from everyday writing, education and publication making Itanigawan a purely spoken language. (Irish, Italian, French and Japanese are not banned from everyday writing, education and publication.)
 * 1946: After the United States of Gooperland (now Gooperland) gained independence from Japan, the ban on writing in Gooperlandian languages has been lifted, and Cyrillic script is used instead of Latin script. Cryillic script became official with Itanigawan language.
 * 1979: Latin script returns.
 * 1986: Some letters that are non-Latin script have been replaced with Latin letters to facilitate printing and computer use.
