Just 3 scripts represent 90% of all registered IDNs: Latin, Han (associated with Chinese language), 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 37%, 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 38%, and Cyrillic script which has declined by 1% to 14% since 2014.
The change in Latin script is in part attributable to the relatively high growth in top level IDNs within the new gTLD space. In top level domains, Latin script accounts for only a minority of registrations. As the proportion of top level IDNs grows, so the percentage of Latin script IDNs relatively declines.
