Rich text characters (8-bit) (like curvy single quotes) don't render correctly on the front panel display of the B2. But the metadata is recorded correctly because the web interface shows the 8-bit characters. Would it be possibly to run a simple filter to convert the most common 8-bit characters to the usual 7-bit conversions? That would make the front panel display less goofy looking.
And no, I'm not going to fix them by hand, since the 8-bit characters seem to be used exclusively in the metadata the is loaded on device and downloaded.
