Problem with some translations?
Fragment of a discussion from Support/LiquidThreads
Therefore showing 3 boxes in https://phabzilla.wmflabs.org/file/data/446pudqx5r4ac3xinuga/PHID-FILE-4mvrbggh4yic6blxbf2b/pasted_file is also expected? Or which font should I install now in order to render those correctly?
I don't know why they are showing to you as boxes, but it is a MediaWiki core change that changed < and > symbols to unicode symbols (e.g. ⧽) to avoid confusing them as html tags. If those appear in the interface, then something is broken, so it should not matter whether they exist in your fonts or not.
