crazydiseases hardens Word redline handling against Microsoft's hidden byte

When you save a Word document, Microsoft tooling often slips an invisible byte at the very start of the file - a marker that signals the text encoding. crazydiseases caught a case where Mike's tracked-changes machinery didn't account for it: the marker tripped a check, the system added a duplicate formatting instruction, and the resulting file came out malformed.

The fix strips that hidden byte before the check runs, so redlined documents stay valid. It's narrow and purely defensive, but it touches the exact path that produces Word files with tracked changes - the format legal teams actually exchange. If your workflow leans on machine-generated redlines going back and forth in Word, this is the kind of quiet correctness fix worth having.
