ERROR: could not convert UTF8 character to ISO8859-1

[JP Glutting <jpglutting@xxxxxxxxxxx>]

I have seen several people with this same error. I get mine when trying 
to backup using pg_dump, causing my backups to fail.

I am using PostgreSQL 8.1 on Windows XP.The databases are in UTF8. I get 
the same error from the command line and using pgadmin3.

Has anyone found a solution for this? Looking around online, I see that 
this supposedly codes for a lowercase a with a circumflex (which I don't 
have in tha table thet triggeres the error), but that this may be the 
first part of a three-byte sequence that codes for something else.

Does anyone know of a way to pinpoint the character in the database? I 
am not sure how to search for a raw unicode character through psql or 
pgadmin...

Thanks for any help!
