More symbols commonly used on Linux

For my fish prompt:

• ✭
• ═

Also look into check marks and crosses of dingbats ( https://unicode-table.com/en/blocks/dingbats/ )

Should some of those symbols be implemented as double width glyphs?

How are double width glyphs supposed to be implemented, such that the font stays monospaced?

Use the original Mononoki i for this (and circle it(?))
