Hello all, I am running a mediawiki instance on my server (Arch Linux). However, it seems that when using HHVM, LanguageConverter behaves differently than what it would on Zend. Symptoms include random unprintable characters appears on rendered pages, line breaks randomly. Since Chinese projects are running on HHVM (without problems), I wonder if there are any caveats I need pay attentions to? Best, mys_721tx
