Is it possible to bevel (or round) a bezier vector handle? I'm trying to match bezier curves to letters (trace them) so that I can make a neon sign, however the font that I'm trying to use has multiple sharp edges that can't exist (because there are no sharp edges on neon signs). For now, when I encounter a sharp edge, I just do this: 

I round them out with simple "Aligned" handle types. However, this method is slow and imprecise, and because I have to eyeball it, it would likely be noticeably different for every letter. Is there any method I can use to round out a "Vector" handle type? They match the sharp corners of edges very well, but I can't have the corners remain sharp.
You cannot use Bevel on a curve. You can, however, bevel a mesh and convert it to a curve. 

I used a cube to create this shape, deleted all but one edge loop, and used Alt+C in Object mode to convert to a curve.
