How to automatically get a font with the desired unicode sequence?

Question

Fonts

Hello!
How to automate the process of creating font files with the desired unicode sequence?
What a task - I have a multilingual site on which the main font is Open Sans.
The task is the following:

1. Need to download the main font file
   
2. Set the unicode sequence of characters that I need from it for each language
   
3. Write font-face with the necessary rules for each received file
   

Are there any ready made solutions? I looked at postcss-font-magician , but, as I understand it, it lacks such functionality (in particular, cut the necessary files from the source).
What can you advise?

Answer 1

Connect it via google fonts, there the font is already cut into unicode-ranges
