Assign a text object to an identifier, then use the min_extent and 
max_extent functions to find the dimensions of the resulting object and 
scale it accordingly as you add it to the scene:


#declare Letter = text {ttf "arial.ttf","~",1,0}

object {Letter
  translate -min_extent(Letter)
  scale 1/(max_extent(Letter)-min_extent(Letter))
  pigment {rgb <1,1,0>}
}

box {-0.001,1.001 pigment {rgbt 0.7}}


Though you don't need it to, this should work the same with a 
multi-character string and should work reasonably well with a lot of other 
POV-Ray objects to boot. These functions actually measure the bounding box 
of the object, but I think that the bounding box aligns pretty well with the 
actual extents of a text object (I didn't yet notice any big differences). 
It doesn't align very well with certain CSG objects and I hate to think what 
would happen with infinite objects such as planes :-)
