Install extra fonts

When text is rendered by a computer, sometimes characters are displayed as 口 a.k.a “tofu”. They are little boxes to indicate your device doesn’t have a font to display the text.

The answer to “tofu” is following:

docker exec -it url2pdf /bin/bash
apt-get update
apt-get install -yq fonts-symbola      # 🙄🙄🙄
apt-get install -yq fonts-noto-cjk     # 囍, 언문, にほんご
apt-get install -yq fonts-ocr-b        # PASSPORT FONT

“no more tofu” !!!
