How to add an icon to the bash prompt

Question

I know you can edit the bash prompt permanently by editing the PS1 variable in your ~/.bashrc file, mine looks like this:

PS1=\"\\[\\e[0;31m\\]

        

Answer 1

The closer you'll get are white and black flags:

⚐ → U+2690 ; WHITE FLAG
⚑ → U+2691 ; BLACK FLAG

The above are Unicode characters. You could also look for a font with flags - I don't know of any.
