How embed font with TrueTypeFontImporter

I want embed a font in a Unity project for work with dynamic text Mesh. I think that I must use TrueTypeFontImporter, but I don’t know how use it. I only know that I must use a C# script and I need the line “using UnityEditor”. Do you know how I can write this?
Thanks for your help!

Dynamic fonts in Unity can have the font embedded, see Unity - Manual: Font assets.

Thank you very much Graham! It works now! I have put the font file in Assets folder. I have used the font texture (included in font file) for create a new GUI/TextShader material.
