From (gnu packages fonts):

  (package
    (name "font-cns11643")
    (version "98.1.20180605")
    (source (origin
              (method url-fetch)
              (uri "http://www.cns11643.gov.tw/AIDB/Open_Data.zip")


Given that Open_Data.zip has a history of being modified in-place,
maybe it would be a good idea to use the Internet Archive Machine instead?

Latest version current in the archive: 
https://web.archive.org/web/20211004150815/http://www.cns11643.gov.tw/AIDB/Open_Data.zip

On <https://web.archive.org/save/http://www.cns11643.gov.tw/AIDB/Open_Data.zip>,
I requested a fresh archival, but it will take some time to complete.
