[DUG] D2007-D2010 upgrade issue

[Alister Christie]

This looks like a unicode issue - is the Grower field a unicode field in 
your database.

I had a similar issue with porting a database from the BDE to firebird 
under D2009 - I just made the firebird database use the ascii characters 
rather than utf-8 or what ever it was using by default.
