Ganesh Acharya posted the link already. You just need a file, it does not matter if you want to use a font file from google or a local company specific font file
“[...]place the fonts folder into the /theme/web/ folder of your Mendix app. Make sure that open-sans.css and the font files are located directly in the /theme/web/fonts/ folder of your Mendix app. [...]”
Open your Mendix app’s theme/web/custom-variables.scss file and locate the following line:
$font-family-import: "https://fonts.googleapis.com/css?family=Open+Sans:300,400,600,700"
Replace that line with the following code:
$font-family-import: "./fonts/open-sans.css"
Then, save your changes. Run your app and you should see fonts rendered correctly
