Faraway unicode symbols (☢,⚙, …) not displayed.

When I enter this:
echo "☢☢☢" | lemonbar -f "hack:size=8" -p
It shows nothing. My font (hack) has the glyph.

Is it something related to multibyte utf8?

I opened a new issue on your fork as I suspect it is associated with XFT. If, not, I'll report it in the original repo too.

Are you sure that hack contains a glyph for ☢ or ⚙?
XftCharExists returns false for the UTF16 character 0x2622 (☢) and hack from ttf-hack, installed from Arch repos.

If you, for example, run lemonbar-xft with DejaVu Sans it displays ☢ and ⚙ correctly (since they are three byte sequences in UTF8).

Oh! So it would mean that when I enter these character in my terminal, they are replaced on-the-fly from a backup font? Possible, I actually hadn't checked.

My bad…

Would it be be hard to have this fallback mechanism for missing unicode characters in the font that is used?

Fallback fonts are one of the reasons this fork exists. Using multiple fonts does just that:

echo "test☢" | lemonbar  -f "hack" -f "dejavu sans" -p

Oh cool!! I didn't know!!
