Dear IRT members, We would like to inform you that the public comment on Han Script Single Character IDN Generic Top-Level Domains is opened at https://www.icann.org/en/public-comment/proceeding/seeking-input-on-han-scri.... Some context: ICANN org worked with the Chinese, Japanese, and Korean Script Generation Panels (CJK GPs) to seek their guidance on string similarity concerns for single character IDN gTLD applications in the Han script. The CJK GPs agreed that the work already done in the Root Zone Label Generation Rules (RZ-LGRs) sufficiently addresses the technical and linguistic concerns around string similarity for single character IDN TLDs. Feedback is requested on the Proposed Considerations for the Application of Single Character IDN Generic Top-Level Domains<https://www.icann.org/en/system/files/files/proposed-han-script-single-chara...> based on the analysis and conclusions shared by the CJK GPs. Best regards, Elisa
