I got incredibly accurate output on my terminal emulator using a nerd font (st with Iosevka Nerd Font, tmux, links2 browser).

Out of curiosity I checked with lsof, apparently other fonts are used as fallback:

/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf

/usr/share/fonts/truetype/droid/DroidSansFallbackFull.ttf

/usr/local/share/fonts/MS/segmdl2.ttf

/usr/local/share/fonts/MS/seguisym.ttf

/usr/local/share/fonts/nerd/Iosevka/IosevkaNerdFont-Regular.ttf

/usr/local/share/fonts/nerd/JetBrainsMono/JetBrainsMonoNerdFontMono-Regular.ttf

At least the result is perfect!
