Just curious how ubiquitous access to the letters a-z are on phones around the world for an authentication system I am working on.<p>Can an android user with a thai or vietnamese keyboard easily access a-z?
The phone itself might have access to the a-z, but the people using the phone might not be comfortable using it, or even being able to recognise it.<p>They could be as comfortable with the a-z as westerners being comfortable using (say) Arabic script would be.
