If so, please provide
related language settings (uselang / preferences etc).

And if user is not logged in, this is even tied to browser language settings. Please provide them too.

We did earlier today a fix to the banner, I asked them if they still have the same issue.

Did anyone ever get to the bottom of this?

Just sticking to CentralNotice for now, how do we want to do this for zh (and other languages with variant scripts)? Automatic conversion or manual translation? At the moment we block translation to the zh-xx variants (barring T51898) so that would suggest the former was the intention.

I just remembered that a few months ago we came across some issues about CN not using language preferences as expected, so maybe that's the explanation for the issue with the original WLM campaign, which did target logged-in users! I'll check it out in detail. Still doesn't solve the challenges of using language variant selector info for anonymous users and passing that data further along down the donation chain...

Another idea: maybe we could create a test campaign on the beta cluster with a setup more or less similar to the one that's needed? What do you think?

Thanks!!

For references, the two projects we talked about that have drop-down variant switchers are Chinese and Kazakh. Are there more?

For both projects, the language variant is shown in URL, though in different places.

On the Kazakh Wikipedia there is a CentralNotice campaign running right now, and its content doesn't change with the variant switcher.

Please note my project https://github.com/adamwight/LanguageTag (also in the WMF repo). It supports IETF language tags, and can convert from MediaWiki or Unix locale yuckiness.

I found a little more info at https://www.mediawiki.org/wiki/Writing_systems There are a few other projects with language conversion, but Chinese is by far the most important one from a fundraising POV.

See also T21044 - the whole area is chronically underdocumented.
