Just 3 scripts represent 90% of all registered IDNs: Han (associated with Chinese language), Latin, and Cyrillic script. Han, Katakana and Hiragana (associated with Japanese language), and Hangul (associated with Korean language) together represent 8% of IDNs. Major world scripts such as Arabic and Devanagari which support some of the world’s top 10 most spoken languages are barely represented in IDNs.
Since 2014, there has been a relative increase in the proportion of Han script domains from 34% to 48%, Han, Katakana and Hiragana has increased from 2% to 5%. In the same period, there has been a relative decline in the proportion of Latin script IDNs, from 41% to 30%, and Cyrillic script which has declined by 2% to 12% since 2014.
The increased popularity of Han script IDNs is attributable to strong growth of second level IDNs in the Chinese ccTLD, .cn.
