We also experience this on NixOS with GLib 2.82 (https://hydra.nixos.org/build/274413637/nixlog/1), it looks like `g_utf8_next_char` no longer includes a cast to `char*` since https://gitlab.gnome.org/GNOME/glib/-/merge_requests/4016.

Ugh, bisected to 18621b90ef3c1ab31d0d4ac7fd8603826d4d824b (?)

It looks like I can't reproduce this issue with `glib_debug` option off when building glib, the option previously defaults to `auto` in < 2.82 and we have `-Dauto_features=enabled` in our...

@lenemter I started looking this since I plan to [drop X11 session in NixOS](https://github.com/elementary/session-settings/issues/91) very soon. I believe my case is not a duplicate of https://github.com/elementary/gala/issues/2505 since I cannot reproduce...
