My Firefox has apparently lost Unicode support for Arabic, but only for Arabic: Persian letters (which AFAIK use the same alphabet!) display just fine. The attached screenshots show the problem via Wiktionary excerpts. Note that while the Arabic text appears only as boxes, the Persian, Azerbaijani, Ottoman Turkish, etc. texts all work just fine. It's clearly not a problem with encoding more generally -- languages as rare as Old Persian, Avestan, and the IPA appear normally. For some reason it's only Arabic that's broken.
What's going on here? How can I fix it?
