I can't find how to change the IDE language **from Arabic** to English, **it selected depending my system** (Windows here)
No `LANG` set, the UI is _Arabic_, not English.

No `LANG` set, yet locale is detected and UI language selected appropriately.
It is clear that Geany used the user-selected locale in Windows, until somebody broke it. It is a bug and should be fixed.
