remove ^B characters

Hi there,

I've got a problem with ^B characters stored in some mysql tables. In
the backup of my DB I read something like that with vi:

INSERT INTO f_ergebnisse VALUES (.....,'^B25^B'......);

What are these ^B characters? Blanks?

So I've tried to remove them with this line in my php script when
printing them out:

while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
$line = str_replace("/\r\n|\r|\n/", " ", $line);
... }

But those annoying characters will not get removed.

How do I get rid of them?

Thanks in advance
