Dear Anthony, (cc Mr. Chen Zhuang and Ken) I find your email in the GB18030 page in IANA (https://www.iana.org/assignments/charset-reg/GB18030), which the page is compiled by you. The newest version of GB 18030 has been published as GB 18030-2022, please see https://std.samr.gov.cn/gb/search/gbDetailed?id=E4A2A4C875726A5DE05397BE0A0A... and https://openstd.samr.gov.cn/bzgk/gb/newGbInfo?hcno=A1931A578FE14957104988029... . However the IANA information has still kept for the original 2000 version, which is not better for the users. CESI also kindly released the mapping table at http://www.nits.org.cn/getIndex.req?action=findAllNews&req=modulenvpromote&t... . If it is not convenient to download the file from the website, you can find the attachment. I think it is better to update the information in corresponding IANA page. So, do you know how shall we need to do? Eiso
