I'm having issues connecting to the site, and nyaa is long gone. @sl1pkn07 Are you able to reupload, or can someone confirm that the site does actually still work?

I don't actually know much about font internals, but I noticed that when using other combinations then 'rt' eg 'rrt",'rd',… everything is displayed as expected. I'm guessing it might be the same (or asimilar) issue as #136 .
The same placeholder glyph is being rendere in pluma when using the packed "Drawing with Markers" Font. So this is probably not a libass-specific issue, but either an issue with the font itself or (lesss likely) an issue with freetype.
Does somebody know how to check if the font is valid ?

Also this should be the relevant lines:

Right, the font contains a contextual ligature for “art” that replaces the “r” with an undefined glyph. Thanks! Closing this in favour of #136.

(I used FontForge to check this.)
