I didn't find a solution in the issues so i installed the docker image.
The text rendering is working now.

fontconfig 2.12.3-1 and libfontconfig.so.1.9.3 are installed.
I will look through the issues now.

I did a fresh install of node.js, npm and jsreport on a host running Arch Linux.
Now when i render the examples with phantom-pdf every text character is rendered as a black box.
The text looks like ◼◼◼ ◼ ◼◼◼◼◼ ◼◼◼ ◼◼.

I have installed imagemagick like suggested from an older github thread and i've installed phantom-js 2 but no luck with that either.

Does anyone have a solution for this problem?
