If "�" is the record seperator then use the record seperator variable
($/) to get the individual records:
{#create a new scope to prevent changes from effecting everthing else
local ($/) = "�";
while (<FD>) {
chomp; #get rid of "�" on the end;
do_something_with_a _record($_);
}
} # $/ goes out of scope and everyone is happy
