Import db from 8.1.3 to 8.3.1

Hi All,

I am trying to import db from 8.1.3 to 8.3.1 database however I get
some characters  \x09\x09\x09\x09.

I know this is an error in 8.3.1 that was fixed in later updates
however is there a way of getting around it without going all over
again and remain with 8.3.1 database where I have already put alot of
important data.

peter.
