Wherever the text is coming from, it's been exported as zillions of small line segments (sometimes called a poly line), not splines. There are tons of small errors where the line endpoints are not coincident, and you're not going to be able to extrude this without a lot of clean up.

I would highly recommend going back to the source and figuring out better export settings.

I bet the source is Adobe Illustrator.
Solution, export from Adobe as Ai or SVG
Import in Inkscape, opensource 
Export from Inkscape as DXF, there are a few option's to try.
Good luck

It should be possible to export from Illustrator (or Inkscape if you don't have Illustrator) as DXF and get good results. You may need to experiment with the options.

In the past I would often need to ungroup and get rid of compound paths in Illustrator, and then export to AutoCAD DXF (not poly lines) with it set to not the latest version (I think 2005 or something).

I don't have Illustrator at the moment to test. As @dirk_van_der_vaart mentions, you can also use Inkscape to save as DXF.
