Adjust text file reading/detection

In my game, I want to add stroke to the some textMesh for my game. I figured out how to export the text from Unity, add the stroke, and put it into a material and Textured font shader.

However, because I'm guessing it reads every character in the text file to exact dimensions, it doesn't transfer very well and ends up looking like this.

As you can see, some of the edges get cut off and it looks really choppy.

How do I fix this to make the text read about a pixel or more farther for every character so that it gets the entire stroked character?
