Boolean with text without conversion I'm trying to find a way to make boolean operation between a mesh and a text with a solidify modifier without applying a conversion to the text.  

I could copy the text, convert it to a mesh, then apply boolean modifier with this copy, but i lose the ability to change the text easily without repeating those operations. 

Any idea?
You can use the booltron addon for this. It works with Curve and Text objects, but it isn't a modifier, it is a command. You select objects for a boolean operation (you can select more than 2) and press the operation name (intersect / difference / union).

Also, booltron fills holes before intersections. 

This is the magic (I added a shortcut for the difference operation):
