David Chan from the Editing Team has written up a nice summary
<https://meta.wikimedia.org/wiki/User:DChan_(WMF)/Forms_of_writing_used_in_Chinese_editions_of_Wikipedia>
of what's going on in the Chinese Wikipedias, discussing the languages,
writing systems, and tools used to deal with them in the eight Wikipedias
people might refer to as "Chinese" (seven modern languages plus Classical
Chinese).
Good stuff!
