The US and UK keyboards are fully supported, as are most other keyboards with Latin alphabets.
However, languages that use special characters such as áéíóí or äëïöü, including umlaut, are not fully supported yet because the exact character won’t show. Languages like Arabic that do not utilize Latin alphabets are not properly supported either.
However, we are working on supporting all the major language keyboards.
