htop uses glyphs from the Unicode Braille Patterns block, but it seems that Source Code Pro doesn't have these. Could they be added?

this seems to be beyond the scope of the project, but i will leave your request here and see if there are more interested parties.

nodejs-dashboard also uses this character set to render graphs in the terminal

While not a crucial feature, it would be nice to have it for BTOP: https://github.com/aristocratos/btop
