12. A computing device, comprising: one or more processors configured to: determine one or more scripts in which a user is capable of inputting text, and determine whether at least one of the one or more scripts is a script having a right-to-left (RTL) writing directionality; and a display configured to automatically output: (i) a first user interface when at least one of the one or more scripts is a script having an RTL writing directionality, wherein the first user interface is configured to allow the user to adjust writing directionality at the computing device, or (ii) a second user interface when none of the one or more scripts is a script having an RTL writing directionality, wherein the second user interface is different than the first user interface and is not configured to allow the user to adjust writing directionality at the computing device.
