[CentOS] get unicode ranges from a TTF ???

Hello list,

Is there a command line tool I run on a ttf font and get a list of the 
Unicode Ranges for that that font that would be compatible with the 
unicode-range: parameter in a CSS @fontface declaration?

I'm guessing something in the python world probably exists...

Hopefully something that works in CentOS 7

I need something like that for a FLOSS font server project that doesn't 
track users.

I don't feel a need to split up a font by unicode range, but a lot of 
fonts are already split by their upstream developers according to 
language support - e.g. the Noto Fonts, the main font has a lot of 
glyphs but Hebrew for example is in it's own font file already.

I want to be able to get the range information for what the fonts support.

Thanks for any tips.

My font server project I need it for is at
