Second-Level Label Generation Rules (LGRs) with Full Variant Set
ICANN has developed second-level Internationalized Domain Name (IDN) tables in machine-readable format or Label Generation Rules (LGRs) with full variant sets so RSPs may use them to expedite IDN Evaluation.
These LGRs have been developed using the Second-Level Reference Label Generation Rules with full variant sets to accommodate any combination of the languages and scripts offered under a TLD. If you have questions or feedback regarding these LGRs, please send an email to IDNprogram@icann.org.
