I got the same result:
FBURL;ENCODING=QUOTED-PRINTABLE:????????????????????b?=03?=03?=03?=0B?=1 F?A?=03?A?A?=03?A?=03=0DZD=01
?=F7

By any chance are you using the IE7 beta? I am on this machine so I wonder
if that's causing trouble.

Just created a fresh contact "New Contact" with title "Limited Data" and
an
Internet Free/Busy of "http://www.aaaaaa.com/FreeBusy/Kaaaaa.vfb" that
turned
it into "http://????????????????????b/FreeBusy/Kaaaaa.vfb" in the vCard
file.
Is it just me or does it do the same thing for you?
