This is terminal-specific - these characters are spaced correctly outside of the terminal.

You can see this particularly well with this single character: ﷽ (U+FDFD). Though to be fair, few apps manage this 'character' well.

This has been fixed for main|✚2… in the terminal but ultra-wide characters like ﷽ are still render overlapping.

echo 'main|✚2…'; echo 1234567890; echo "﷽234567890"
