How I install specific fonts on my AWS EC2 instance?

I have a Python application running on an AWS EC2 (Amazon Linux, Elastic Beanstalk) instance that requires certain specific fonts to produce output and wonder how to install them as part of the deployment or instance launching process.

My code, running on my local machine (OS X) uses

'Arial Unicode MS'
'Open Sans'

as fonts. But these fonts are not present by default on EC2 (I only see DejavuSans and DejvuSerif in /usr/share/fonts), and it is not clear to me either what packages might include the fonts I need, or how to install them.

How do I install those two fonts on EC2, preferably using yum or a command or container_command as part of the deployment/instaitation process specified on an .ebextensions/*.config file?
