 produces <code>TextLayout</code> objects.  The text must contain at
 least one character.  If the text available through

       Text measurements can vary slightly depending on the
       device resolution, and attributes such as antialiasing.  This
       parameter does not specify a translation between the
       <code>LineBreakMeasurer</code> and user space.<DT><B>See Also: </B><DD><A HREF="../../../java/awt/font/LineBreakMeasurer.html#insertChar(java.text.AttributedCharacterIterator, int)"><CODE>insertChar(java.text.AttributedCharacterIterator, int)</CODE></A>,
