On any form of text, whether it be swept text on its own, or text extruding out from an object; certain letters when subdivided really mess up their geometry and I don't know how to sort this out. See diagram below.
The "O" is fine, but the "N" is just messed up.
Help! |

It's to do with the points not being connected. If you use the 'tesselate' plugin in polytools and turn the 'N' into quads it'll be much, much better. Still not perfect and you may have to do a little bit of tidying up but it'll at least look more like the letter it's supposed to be than a melted fridge magnet!
For standalone text that I need to subdivide I usually do this and then boolean subtract a cube from the top and bottom to give clean faces.
Hope that helps |

From what I can tell the text is booleaned into the object correct, if so then you need to add more vertices like TheWickedWitchOfTheWeb said because of the lack of detail when you apply the SDS they collpase on themselves you need to refine it alot more for that, see the image I have included. These lines are just an example of course, of what you need to do.
While you are reading this I might as add I use a program called elefont for all my 3d text, and can be found here did I mention it's free. http://www.armanisoft.ch/webdesign/elefont/Elefont.html

You could also try triangulating it before subdiv. but this leaves slightly rounded and ugly edges when subdiv. In the pic below, adding a couple edges will help to keep it from getting so messed up.
EDIT : I guess my idea would be PRE-Boolean for this particular application :) |

The better and cleaner the topology of the mesh (preferably quads), the better the SDS results. I bet you get similar or same results with any other software. Rather than adding edges around the N like daybe suggestet, I'd connect the vertices on the cap of the N with edges to solve the problem, as that seems to be the area of problems. |

Also you'll want to have two edges close together if you want to maintain a defined edge in SubD mode. So not only do you need to quadify it, you'd need two control lines around all the edges of the "N":
