WPF TextBlock requirement

I have a requirement for my t开发者_StackOverflow中文版extblock to have a character gap of 75 and a border line of 2 pixel. How would I achieve this?

For spacing the characters out you could look at the following: WPF TextBlock: How to evenly space displayed characters?

For border line, i guess wrapping it around the Border element should do the trick.

Hope it helps you or atleast gets you started on the right track.
