How to include a font?

Hello, I bought a text font and want use it on the project, so, any possibility to learn how do I upload it with the font to the game?

After a research about the problem, I saw many posts and tutos saying about web fonts, and others about CSS, but I have no idea of how them work.

The web font didn't worked. I followed the entire tutorial from Ashley and the game won't show the right font, so, I bought another font, and now, I have no clue of how to show it on the game while playing on the internet.

You could turn off webGL and see what happens, sometimes i include custom fonts without webGL it always work. I had no idea, actually bitmap font is an solution.
