elixir gettext current does not fully support fallback to another language [0].
But it might in the future. We adapt it so that all languages in Accept-Language
headers are received by Pleroma.Web.Gettext. User.languages is now a comma-separated
list.

For an example, here, zh is not supported, but zh_Hans and zh_Hant
are. If the user asks for zh, we should choose a variant for them
instead of fallbacking to default.
Some browsers (e.g. Firefox) does not allow users to customize
their language codes. For example, there is no zh-Hans, but only
zh, zh-CN, zh-TW, zh-HK, etc. This provides a workaround for
those users suffering from bad design decisions.
For some reason I had a test who suddenly failed, mix test test/pleroma/web/o_auth/app_test.exs:54. A user has a list of applications and this test adds them and then sees if the list it gets back is the same as the apps it added.
When I ran mix test a day before I didn't have this problem and when I pushed code today in a different MR, the pipeline succeeded (see https://git.pleroma.social/ilja/pleroma/-/jobs/205827), yet locally it failed. So it seems the test can sometimes succeed and sometimes fail, which makes it untrustworthy.
The failure I see is because the returned list is in reverse order. I assume that's not per sé wrong. You just want to know if the apps you added are actually there. I fixed the test by first ordering the lists before comparing.
AFAICT (and as far as that's relevant) the test got introduced in commit cb2a072e62
Even though latest PleromaFE supports displaying these properly, mobile
apps still exist, so I think we should offer a workaround to those who
want it.
Elixir 1.13 does not allow them in raw form anymore, resulting in errors
like this when running the test:
== Compilation error in file test/pleroma/web/rich_media/parser_test.exs ==
** (SyntaxError) test/pleroma/web/rich_media/parser_test.exs:136:45: invalid bidirectional formatting character in string: \u202C. If you want to use such character, use it in its escaped \u202C form instead
