Check for a string to be in English using Java

This is useful especially if you are insanely bugged by the smart testers who love international characters being filled at the places where it is not required.

Here is the simple checking code. As always, if you have something better to share, please use comments.

public static boolean canEncode(String s, String cs)
{
try
{
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Writer w = new OutputStreamWriter(baos, cs);
w.write(s);
w.close();
String t = baos.toString(cs);
return s.equals(t);
}
catch(Exception e)
{
return false;
}
}
