How to add double-width nerdspace glyph?

[jkimsis]

Hello,

I'm trying to customize the fastfetch config you posted on Reddit a year ago (https://www.reddit.com/r/GarudaLinux/comments/1dcq0dl/making_fastfetch_more_beautiful_linux/) and I can't figure out how to add a double-width nerdfonts glyph (like the ones used for PC and OS). I can make the ones that are already there smaller by deleting half of it, but not how to add a new one and make it bigger.
