hi! i've installed plantuml in a docker container (next to wiki.js) and want to use it there. and although i have two fonts listed in the "listfonts" example (DejaVu and Noto), they seem to be wrongly rendered. after installing roboto, this new font will also not be listed. restarting the container does not change anything.
now i wonder what i am doing wrong, or where i should put the font files instead. anny ideas?
