How to remove unwanted characters from a font?

Question

Fonts

I want to optimize my sites as much as possible. I need to cut characters from fonts that are not used anywhere.
How can this be done?
The font formats there are very different: woff, woff2, ttf, otf, etc.

--- UPD ---

I found a site that I used for this purpose:
