Dwmblocks doesn't display FontAwesome icons

[isak102]

I have a simple bash script which checks how many updates I have available and prints them with some icons, this is the code for it:

#!/bin/bash

while ! nc -zw1 google.com 443 >/dev/null 2>&1; do
  # holds the script until we have network
  sleep 2
done

# total_updates=$(yay -Qu | wc -l)
pacman_updates=$(checkupdates | wc -l)
aur_updates=$(yay -Qua | wc -l)

[[ "$aur_updates" -lt 0 ]] && aur_updates=0 # if its less than 0 we just set it to 0

# echo "Pacman: $pacman_updates"
# echo "AUR: $aur_updates"

red_bound=20

create_string () {
    count="$1"
    prefix="$2" # prefix is the letter before the symbol

    if [[ $count == 0 ]]; then
        echo "<span color='#0BDA51'>$prefix</span>"
    elif [[ $count -ge $red_bound ]]; then
        echo "<span color='red'>$prefix$count</span>"
    else
        echo "<span color='yellow'>$prefix$count</span>"
    fi
}

pacman_string=$(create_string $pacman_updates)
aur_string=$(create_string $aur_updates "Y")

package_list_path="$(chezmoi source-path)"
yay -Qe | cut -f 1 -d " " > $package_list_path/installed-packages-$HOSTNAME.txt

echo "$pacman_string $aur_string"

And when I use it with xsetroot everything works as expected, the Font Awesome characters get printed as expected. However when I call this script from dwmblocks nothing gets printed at all and the title of my current window gets printed instead:
