What is homoglyph bundling? Does EURid offer it?
Depending on the script and the font used, domain names might look similar. As a matter of fact, certain characters or glyphs have shapes that might look either identical or might be hard to differentiate at first glance. Domain names are considered homoglyphs of each other if all characters of one domain name are homoglyphs of all characters of the other domain names, at their respective positions.
A Homoglyph Bundle is a set of domain names that are all homoglyphs of each other.
Certain registries have adopted policies to deal with homoglyph bundles. The EURid approach is to ensure that once a domain name from a certain homoglyph bundle is registered, it is not possible to register any other domain name belonging to the same bundle.
This approach aims to reduce the risk of confusion created by domain names that may look similar.
Since the launch of the .eu TLD in the Cyrillic script on the 1st of June 2016, the homoglyph bundling algorithm takes legacy domain names (such as юю.eu) into account. As long as legacy Cyrillic domain names (domain names consisting of Cyrillic characters but with the Latin extension) exist, homoglyph bundling will not take the extension into account to determine if a domain name is in the same homoglyph bundle as another domain name.
It is worth to point out that EURid hasn’t allowed script mixing since the launch of IDNs to reduce the risk of having confusingly similar domain names.
