If a user does not see the language switcher icon on their keyboard, what could be a likely reason?

The presence of the language switcher icon on a keyboard is directly associated with the keyboards that have been enabled or installed on the device. If a user does not see this icon, it is likely because they have not added or activated any additional keyboard layouts. Many operating systems require users to manually enable keyboards for different languages in the settings; without doing this, the option to switch between languages will not be available, leading to the absence of the language switcher icon.

While other factors such as the user’s location or specific settings could influence featured options, they do not directly affect the availability of the language switcher unless there is an additional keyboard that has been set up. Therefore, the realization that the user has not enabled or installed additional keyboards clearly highlights why they may not see the language switcher icon.
