I started with this AI file:

   http://commons.wikimedia.org/wiki/File:Ruby_logo.svg

which claims that it's UTF-8 encoded. The line that gives an error above looks like this in it:

  <?xpacket begin="<U+FEFF>" id="W5M0MpCehiHzreSzNTczkc9d"?>

"<U+FEFF>" the byte sequence of that is 0xef 0xbb 0xbf.

Inkscape will transform that into a single 0xff byte (which is represented as "ÿ" when reported as error on the console) when saving the file.
