This function sets the character callback of the specified window, which is called when a Unicode character is input.
The character callback is intended for Unicode text input. As it deals with characters, it is keyboard layout dependent, whereas glfwSetKeyCallback is not. Characters do not map 1:1 to physical keys, as a key may produce zero, one or more characters. If you want to know whether a specific physical key was pressed or released, see the key callback instead.
The character callback behaves as system text input normally does and will not be called if modifier keys are held down that would prevent normal text input on that platform, for example a Super (Command) key on macOS or Alt key on Windows.
