For your information, on Rafal's advice, I sent a question to glibc
community about new language codes.

Objet: Language code changes over time: zh_CN -> zh_Hans

Hi,
the Fedora community is migrating to the Weblate translation platform.
This translation platform uses zh_Hans, zh_Hant, zh_Hant_HK by default,
instead of zh_CN, zh_TW and zh_HK.
If I understand correctly, we need to make sure the language code exists
in glibc before deciding using the new code for Linux applications.
The issue is as follow: a translation platform can be used by many
projects, not all using glibc, like Websites or mobile application who
already are using the new code.
The web tells that the codes zh_CN, zh_TW, zh_HK are old codes and
should be replaced by the new ones.
Multiple sources tends to confirm this (and show that other actors
already did the move), the most relevant ones are:
https://www.w3.org/TR/i18n-html-tech-lang/#h2_langvalues
http://www.rfc-editor.org/rfc/bcp/bcp47.txt
And the replacement rule is also in the CLDR:
https://github.com/unicode-org/cldr/blob/ed7854cb6209678739712854a2df1cac732be540/common/supplemental/supplementalMetadata.xml#L177
What is the support status of these new language codes in Glibc?
If not supported, can we imagine to have backward compatibility while
upstream projects migrate to the new language code?
I assume these are not the only language code renaming, what policy do
you suggest concerning these?
Please do not hesitate to tell where this discussion should happen as
this is my first contact with your community.
Thanks a lot for your help,
Jean-Baptiste
