The characters look binary, so this might be a problem of conversion latin1 -> utf8 or vice versa.
Try dumping with:
mysqldump --default-character-set=binary ... >/path/to/dumpfile
And loading the dump with:
mysql --default-character-set=binary ... >/path/to/dumpfile
Let us know if that works.
HTH,
thanks for all the suggestions - in the end i opted for rsyncing the datafiles for this db and for me this worked fine. Not the 'correct' way but one that worked OK at the time.
thanks
