1. Type “Madry”.
2. Realize that the a has a little tail that you need to include.
3. That’s a feature of the Polish alphabet called an ogonek.
4. You type it in LaTeX like so: M\k{a}dry.
5. You get the error “Command \k unavailable in encoding OT1”.
6. That’s because you need LaTeX to use a slightly different font package.
7. In your preamble, add \usepackage[T1]{fontenc}.
8. You’re done.

My thanks to the Stack Exchange articles about how to use that symbol and how to deal with the LaTeX error I got implementing that fix.
