extract-audio crash on special chars in video title from Youtube

[esamo]

Hello again.

At Win7 x64. It seem to be ffprobe problem but can be fixed at youtube-dl before executing ffprobe. Probe from http://ffmpeg.zeranoe.com/builds/

1. Is there an option for youtube-dl to remove special chars from Youtube's video title? Extract-audio option doesn't work for squares etc. in title. At least those chars are shown in Windows 7 as squares.
2. Or is it a bug?

Pasting the issue below. Everything works fine when there are no 'squares' in video title.

Now I am able to download audio format alone without video, the simplest and fastest option.

It's achieved by youtube-dl -f 141 VIDEO_URL, though when the format is not available, can be examined by -F option.
