Yes something along those lines.

Hi,
The correct fix is to change the script make-usb.py in the tools dir to escape non ASCII chars
similarly to make-sminmpec.pl
sub escape_non_ascii {
    my $val = unpack 'C', $_[0];
    return sprintf '\0%.3o',$val;
}
and rebuild the file, then submitt a patch with the changes.

Hi,

with the following patch:

"SideWinder® Freestyle Pro" is now displayed as "SideWinder\\xc2\\xae Freestyle Pro". I guess this is the kind of escaping you were thinking to Anders, right?

Note that I'm a newbie in Python so there might be a smarter way to do it. If nobody propose something else, I will push it as is and let the Python experts do a follow up if needed.
