title: Limit languages in Android/iOS for input text
body: <p>Is there any way to limit the input text of edittext to english and hebrew only?
  Since data is transferred to a server SQL DB, and I do not want to store other languages....
  So is it a way to limit to specific language input?</p>
  
  <p>Or maybe there is other way to handle these situation so server will not crash...</p>
