Hi Tobias, We strictly follow the Unicode rules here. So if new Unicode versions include this update, then it will automatically work in the future. If Unicode does not update, I don't believe there is anything we can do, because then we would no longer be Unicode compliant and diverge from all other tools and languages out there.
There is typically a new Unicode version every year, around September, so maybe it will be addressed once it is out and we update Elixir files! *José Valimhttps://dashbit.co/ <https://dashbit.co/>* On Wed, Apr 9, 2025 at 10:46 AM Tobias Pfeiffer <prag...@gmail.com> wrote: > Hello all and thanks for all your work. > > This isn't super important, but after wondering how ß, a German character > that notoriously has no capital version, was treated I found a bit of a > rabbit hole and found out that apparently since 2024 it _has_ a capital > version "ẞ" which is now preferred.
