Korean input problem on macOS

[song9063]

I can't write with Korean well, because when I type any special characters after Korean character, Geany replace the last Korean character to special character.
I'm using macOS Monterey 12.5.1, Geany 1.38(Using GTK+ v3.24.30 and GLib v2.68.0 runtime libraries)

OK, the screencast is very blurry so I can't read it well and see what's happening (and in the first place, I don't even know what exactly it should do). In any case, it's most probably a GTK bug and not a bug of Geany itself. I made some more recent builds with newer versions of GTK which might help:

Geany 1.38:
https://download.geany.org/snapshots/geany-1.38_osx-5.dmg
https://download.geany.org/snapshots/geany-1.38_osx_arm64-2.dmg

Geany 1.39git:
https://download.geany.org/snapshots/geany-1.38_osx.dmg
https://download.geany.org/snapshots/geany-1.38_osx_arm64.dmg

Another thing you can play with is this settings in ~/.config/geany/geany_mac.conf

# no value: don't use any IM module; module name: use the specified module, e.g. 'quartz' for native macOS behavior, for complete list of modules, see Geany.app/Contents/Resources/lib/gtk-3.0/3.0.0/immodules, use without the 'im-' prefix
im_module=quartz
