how to erase the origin data?

[waterloo <waterloo2005 gmail com>]

now I have changed my directories structure and changed names to utf8.
but I find that beagle always remember original directories with beagled --fg --debug.
It says :  Delaying add of ... until FSQ comes across it .
but that directory doesnot exist.
that original file name uses non-utf8 ,so it always makes beagle halts and exits. 

HOW to make beagle working freshly .
I mean to erase all original data that is remembered by beagle.

thanks
