Remarks

This method is called when the buffer is going to replace the range dstart … dend of dest with the new text from the range start … end of source. Return the CharSequence that you would like to have placed there instead, including an empty string if appropriate, or null to accept the original replacement. Be careful to not to reject 0-length replacements, as this is what happens when you delete text. Also beware that you should not attempt to make any changes to dest from this method; you may only examine it for context.

Note: If <var>source</var> is an instance of Spanned or Spannable, the span objects in the <var>source</var> should be copied into the filtered result (i.e. the non-null return value). TextUtils#copySpansFrom can be used for convenience if the span boundary indices would be remaining identical relative to the source.
