I'm trying to create a gravestone with chiseled text on it.
I have a cube (the stone) a text for which I added some depth and bevel, and then converted to a mesh.
I positioned the text so that it's partly "inside" the cube and tried adding a boolean difference modifier on the cube (cube - text), so that the text would be chiseled in the stone.
This gets Blender crazy. Initially nothing worked. I used a decimate modifier on the text to reduce its complexity, and now A few letters are chiseled, the rest are not.
This is how things look when Both the cube (headstone) and the text (now a mesh) are visible (there's another grave base object, but we can ignore it):
The gravestone has the boolean difference modifier, and if I hide the text, this is what I see:
What can I do to make this work? I don't actually need to render this scene, I want to convert it to an STL file and 3D print it.
More info: As stated in the comments, this is due to the text being non-manifold. Actually, it has 2000+ non-manifold edges!
If I try to remove doubles, it just deletes the entire text. No matter what the double threshold is (tried 1mm, 0.1mm, etc. - I'm working with metric units).
Any suggestions on this?

This time, I've used the remesh modifier, but it only worked for one text object (converted to a mesh and remeshed), not the other two. The difference between the one that works, and the others that don't is that for the first one I used Octree depth = 7, and for the other two I used Octree depth = 8 (as 7 wasn't smooth enough).
To test this, just replace the object used in the boolean modifier of the cute from 'RIP' (which works) to either 'iGoogle' or 'years', which don't work.
