Mor1arty unblocks Chinese-language file uploads

The fix is narrow but pointed: it sits in the file upload path, not the display layer, which means the problem was happening at the moment documents entered the system - bytes being read or decoded under an assumption that quietly held for English text and broke the moment multi-byte characters showed up.

There's no write-up attached, just a commit message naming the symptom, and Mor1arty merged it within four minutes of opening the change. That cadence tells its own story: this is a self-maintained fork being patched to unblock a real user trying to feed in Chinese-language documents. It isn't a translated interface or a localization push - it's the more fundamental step of making sure the system can accept the files non-English users actually have.
