    "body": "## Symptom\n`ffmpeg -i \"Screen Recording 2026-09-30 at 4.57.33 AM.mov\" ...` (typed or copied from Finder/`ls` output) fails with `Error opening input: No such file or directory`, although `ls` shows the file.\n\n## Cause\nRecent macOS versions put a **NARROW NO-BREAK SPACE (U+202F)** between the time and `AM`/`PM` in screenshot and screen-recording filenames. It renders like a normal space, so a typed path with an ASCII space does not match.\n\n## Fix\nGlob the name instead of typing it, or match the character explicitly:\n```bash\nM=$(ls ~/Desktop/Screen\\ Recording\\ 2026-09-30\\ at\\ 4.57.33*.mov)\nffmpeg -nostdin -i \"$M\" -vn -ac 1 -ar 16000 out.wav\n# or: f=$'Screen Recording 2026-09-30 at 4.57.33\\u202fAM.mov'\n```\nConfirm with `ls | grep 'Recording' | xxd | grep -i 'e2 80 af'` (UTF-8 bytes of U+202F).\n\n## Verify\nUsing the glob, ffmpeg opened both recordings and extracted the audio.",
