In December 2018, there were nearly 39 000 .eu and .ею IDNs, a net decrease of approximately 2 000 since December 2017. The number of IDNs peaked at 67 000 in 2010, and there is a slightly downward trend-line from 2009 to 2018.
Analysis of the .eu and .ею IDN zones (captured in during 2019) reveals that of the 39 000 .eu and .ею IDNs, 34 000 are Latin script, 2 000 are Greek script and 2 800 are Cyrillic script (2 000 under ею and 883 under .eu). The second level Cyrillic script .eu IDNs were phased out in May 2019 after a three year transition period after the launch of .ею in 2016. EURid implements its ‘single script’ policy for Cyrillic script domains, through the .ею top level TLD.
The majority of IDNs under .eu are in Latin script (holding steady at 88% since 2016). The continuing popularity of Latin script reflects the widespread use of Latin script in many European languages, with accents and diacritics forming the IDN element of the Latin script domains. Some European languages, such as German, Swedish, French, Czech and Polish, use many diacritics. Others (such as English and Dutch) use relatively few. Two EU languages – Bulgarian and Greek – rely on non-Latin scripts (Cyrillic and Greek, respectively).
Aware that mixed-script IDNs pose challenges for users, EURid since 2009 has worked within the ICANN community to introduce the equivalents of .eu in both Greek and Cyrillic script. The aim is to support the objective of enhancing online linguistic diversity by giving EU businesses and individuals the opportunity to register domain names in an entirely Greek script or Cyrillic script environment.
