Script of second level IDNs

At the second level, Latin script dominates, with 55% of second level IDN registrations; then comes Han (29%), Han, Katakana and Hiragana (8%), and Hangul (4%). All other scripts, including Cyrillic, Arabic, Devanagari (with hundreds of millions of speakers offline) represent fewer than 4% of second level IDNs. The dominance of Latin script in second level IDNs can be explained by the good fit between a Latin script IDN (usually with accents or diacritics) and an ASCII TLD, where ASCII is a subset of Latin script. For example, for Viet Nam, Germany, France, or Turkey, whose languages are based on Latin script, it makes sense to deploy IDNs at the second level under established ccTLDs (.vn, .de, .fr and .tr).

Since 2014, the relative proportion of Latin and Han script second level IDNs has decreased slightly (from 57% to 55% for Latin script, and from 30% to 29% for Han).  There has been a 5% increase in the proportion of Han, Katakana and Hiragana second level IDNs – these scripts are associated with Japanese language.
