How can i show points with this design?

You're talking about adding a stroke around your font? Though you are able to use custom fonts, by dragging the font file into your Assets folder, and then applying it in something like a GUItext object, or a [var name : GUIStyle;] (apply it where the variable in the inspector reads: Font), unity doesn't have a way of adding a stroke to text (the white outline surrounding your example).

This can be faked with multiple versions of your white text with 1 pixel (or so) offsets in the x and y axis, positioned behind your gray colored text.

Some people opt to use materials to fake this, but I'm unsure how to do that, and there is also middle-ware available on the asset store to help you out. Otherwise, there's no way to code it, or flip a switch to make it appear.
