How to underline text in a RTEXT entity?

The RText (remote text) contents can be a Diesel expression or an external file. Control characters are disabled in RText by default. The underline control chars are \L and \l.

To enable processing of control characters (like in MText) also in RText objects, use an undocumented setting - bit 2 in the DXF group 70.

Try e.g. the following code which creates an underlined RText:

  
(entmake '((0 . "RTEXT")  
(100 . "AcDbEntity")  
(100 . "RText")  
(10 10.0 10.0 0.0)  
(40 . 0.3)  
(70 . 3)  
(7 . "Standard")  
(1 . "UNDERLINED {\\LTEXT}") ) )

Make sure you have used the RTEXT command at least once in the current session.
