some people might not know how to make custom fonts in unreal engine. It is pretty simple to do, here is how:
1st: go to this site: http://www.fontsquirrel.com/fonts/list/find_fonts?filter[classifications]=comic&filter[classifications]=sans+serif&filter[classifications]=script&filter[classifications]=stencil
and pick a font you like.
2nd: Go in unreal engine 4 and right click in the content browser, go to user interface, create new Font,
3rd: Open the newly created font blueprint. Open file, Select your downloaded font and click open.
4th: Edit the settings in a way you are happy with it and save the file. Now the font is select able in for example a user interface.
I hope this helped you.
